3 DOSAGE FORMS AND STRENGTHS

COMIRNATY is a suspension for injection. A single dose is 0.3 mL.

4 CONTRAINDICATIONS

Do not administer COMIRNATY to individuals with known history of a severe allergic reaction (e.g., anaphylaxis) to any component of COMIRNATY [see Description (11)] or to individuals who had a severe allergic reaction (e.g., anaphylaxis) following a previous dose of a Pfizer-BioNTech COVID-19 vaccine.

5 WARNINGS AND PRECAUTIONS

5.1 Management of Acute Allergic Reactions

Appropriate medical treatment used to manage immediate allergic reactions must be immediately available in the event an acute anaphylactic reaction occurs following administration of COMIRNATY.

5.2 Myocarditis and Pericarditis

Postmarketing data with authorized or approved mRNA COVID-19 vaccines demonstrate increased risks of myocarditis and pericarditis, particularly within the first week following vaccination. For COMIRNATY, the observed risk is highest in males 12 through 17 years of age. Although some cases required intensive care support, available data from short-term follow-up suggest that most individuals have had resolution of symptoms with conservative management. Information is not yet available about potential long-term sequelae.

The Centers for Disease Control and Prevention (CDC) has published considerations related to myocarditis and pericarditis after vaccination, including for vaccination of individuals with a history of myocarditis or pericarditis (https://www.cdc.gov/vaccines/covid-19/clinical-considerations/myocarditis.html).

5.3 Syncope

Syncope (fainting) may occur in association with administration of injectable vaccines, including COMIRNATY. Procedures should be in place to avoid injury from fainting.

5.4 Altered Immunocompetence

Immunocompromised persons, including individuals receiving immunosuppressant therapy, may have a diminished immune response to COMIRNATY [see Use in Specific Populations (8.6)].

5.5 Limitation of Effectiveness

COMIRNATY may not protect all vaccine recipients.

6 ADVERSE REACTIONS

An overview of clinical studies contributing to the safety assessment of COMIRNATY is provided in Table 1. Participants in these clinical studies received a 2-dose series, 3 weeks apart (referred to as a primary series) and subsequent doses referred to as booster doses.

6.1 Clinical Trials Experience

Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a vaccine cannot be directly compared to rates in the clinical trials of another vaccine and may not reflect the rates observed in practice.

Primary Series With COMIRNATY

The safety of a 2-dose primary series of COMIRNATY was evaluated in participants 12 years of age and older in 2 clinical studies conducted in Germany (Study 1), United States, Argentina, Brazil, Turkey, South Africa, and Germany (Study 2). Study BNT162-01 (Study 1) was a Phase 1/2, 2-part, dose-escalation trial that enrolled 60 participants, 18 through 55 years of age and 36 participants, 56 through 85 years of age. Study 2 was a Phase 1/2/3 multicenter, randomized, saline placebo-controlled, double-blinded (Phase 2/3), dose finding-, vaccine candidate-selection and efficacy study that enrolled approximately 46,000 participants 12 years of age or older. Of these, approximately 2,260 participants were 12 through 15 years of age (1,131 COMIRNATY; 1,129 placebo) and 754 were 16 through 17 years of age (378 COMIRNATY; 376 placebo). In all, 44,047 participants in Phase 2/3 were 16 years of age or older (22,026 COMIRNATY; 22,021 placebo).

Study 2 included 200 participants with confirmed stable human immunodeficiency virus (HIV) infection. Confirmed stable HIV infection was defined as documented viral load <50 copies/mL and CD4 count >200 cells/mm3 within 6 months before enrollment, and on stable antiretroviral therapy for at least 6 months. HIV-positive participants are included in the safety population but are summarized separately in the safety analyses.

In Study 2, participants 12 years and older in the reactogenicity subset were monitored using an electronic diary for solicited local and systemic reactions and use of antipyretic medication after each vaccination. Participants were also monitored for unsolicited adverse events throughout the study (from Dose 1 through 1 month [all unsolicited adverse events] or through 6 months [serious adverse events] after the last vaccination). Tables 2 and 3 present the frequency and severity of solicited local and systemic reactions, respectively, within 7 days following any dose of COMIRNATY.

Adolescents 12 Through 15 Years of Age

In Study 2, 2,260 adolescents (1,131 COMIRNATY; 1,129 placebo) were 12 through 15 years of age. At the time of the analysis of the ongoing Study 2 with a data cutoff of September 2, 2021, there were 1,559 (69.0%) adolescents (786 COMIRNATY and 773 placebo) 12 through 15 years of age followed for ≥4 months after the second dose.

Demographic characteristics in Study 2 were generally similar with regard to age, gender, race, and ethnicity among adolescents who received COMIRNATY and those who received placebo. Overall, among the adolescents who received COMIRNATY, 50.1% were male and 49.9% were female, 85.8% were White, 4.6% were Black or African American, 11.7% were Hispanic/Latino, 6.4% were Asian, and 0.4% were American Indian/Alaska Native.

Local and Systemic Adverse Reactions Solicited in Study 2

In adolescents 12 through 15 years of age after receiving Dose 2, the mean duration of pain at the injection site was 2.5 days (range 1 to 11 days), for redness 1.8 days (range 1 to 5 days), and for swelling 1.6 days (range 1 to 5 days) in the COMIRNATY group.

Unsolicited Adverse Events in Study 2

In Study 2, 2,260 adolescents (1,131 COMIRNATY; 1,129 placebo) were 12 through 15 years of age. Of these, 634 (56.1%) participants in the COMIRNATY group and 629 (55.7%) participants in the placebo group had follow-up time between ≥4 months to <6 months after Dose 2 in the blinded placebo-controlled follow-up period with an additional 152 (13.4%) and 144 (12.8%) with ≥6 months of blinded follow-up time in the COMIRNATY and placebo groups, respectively.

A total of 1,113 (98.4%) participants 12 through 15 years of age originally randomized to COMIRNATY had ≥6 months total (blinded and unblinded) follow-up after Dose 2. An analysis of all unsolicited adverse events in Study 2 from Dose 1 up to the participant unblinding date was conducted. Among participants 12 through 15 years of age who received at least 1 dose of study vaccine, unsolicited adverse events were reported by 95 (8.4%) participants in the COMIRNATY group and 113 (10.0%) participants in the placebo group.

In an analysis of all unsolicited adverse events reported during blinded follow-up from Dose 1 through 1 month after Dose 2, in adolescents 12 to 15 years of age, those assessed as adverse reactions not already captured by solicited local and systemic reactions were lymphadenopathy (9 vs. 2), and nausea (5 vs. 2).

In the analysis of blinded, placebo-controlled follow-up, there were no other notable patterns or numerical imbalances between treatment groups for specific categories of unsolicited adverse events (including other neurologic or neuro-inflammatory, and thrombotic events) that would suggest a causal relationship to COMIRNATY. In the analysis of unblinded follow-up, there were no notable patterns of specific categories of non-serious adverse events that would suggest a causal relationship to COMIRNATY.

Serious Adverse Events

In Study 2, among participants 12 through 15 years of age who had received at least 1 dose of vaccine or placebo (COMIRNATY = 1,131; placebo = 1,129), serious adverse events from Dose 1 up to the participant unblinding date in ongoing follow-up were reported by 10 (0.9%) COMIRNATY recipients and 2 (0.2%) placebo recipients. In these analyses, 69.0% of study participants had at least 4 months of follow-up after Dose 2. In the analysis of blinded, placebo-controlled follow-up, there were no notable patterns between treatment groups for specific categories of serious adverse events (including neurologic, neuro-inflammatory, and thrombotic events) that would suggest a causal relationship to COMIRNATY. In the analysis of unblinded follow-up, there were no notable patterns of specific categories of serious adverse events that would suggest a causal relationship to COMIRNATY.

Participants 16 Years of Age and Older

At the time of the analysis of Study 2 with a data cutoff of March 13, 2021, there were 25,651 (58.2%) participants (13,031 COMIRNATY; 12,620 placebo) 16 years of age and older followed for ≥4 months after the second dose.

Demographic characteristics in Study 2 were generally similar with regard to age, gender, race, and ethnicity among participants who received COMIRNATY and those who received placebo. Overall, among the total participants who received either COMIRNATY or placebo, 50.9% were male, 49.1% were female, 79.3% were 16 through 64 years of age, 20.7% were 65 years of age and older, 82.0% were White, 9.6% were Black or African American, 25.9% were Hispanic/Latino, 4.3% were Asian, and 1.0% were American Indian or Alaska Native.

Local and Systemic Adverse Reactions Solicited in the Study 2

In participants 16 through 55 years of age after receiving Dose 2, the mean duration of pain at the injection site was 2.5 days (range 1 to 70 days), for redness 2.2 days (range 1 to 9 days), and for swelling 2.1 days (range 1 to 8 days) for participants in the COMIRNATY group.

In participants 56 years of age and older after receiving Dose 2, the mean duration of pain at the injection site was 2.4 days (range 1 to 36 days), for redness 3.0 days (range 1 to 34 days), and for swelling 2.6 days (range 1 to 34 days) for participants in the COMIRNATY group.

In participants with chronic, stable HIV infection the frequencies of solicited local and systemic adverse reactions were similar to or lower than those observed for all participants 16 years of age and older.

Unsolicited Adverse Events

Overall, 11,253 (51.1%) participants 16 years of age and older in the COMIRNATY group and 11,316 (51.4%) participants in the placebo group had follow-up time between ≥4 months to <6 months after Dose 2 in the blinded placebo-controlled follow-up period with an additional 1,778 (8.1%) and 1,304 (5.9%) with ≥6 months of blinded follow-up time in the COMIRNATY and placebo groups, respectively.

A total of 12,006 (54.5%) participants originally randomized to COMIRNATY had ≥6 months total (blinded and unblinded) follow-up after Dose 2.

In an analysis of all unsolicited adverse events reported following any dose, through 1 month after Dose 2, in participants 16 years of age and older (N=43,847; 21,926 COMIRNATY group vs. 21,921 placebo group), those assessed as adverse reactions not already captured by solicited local and systemic reactions were nausea (274 vs. 87), malaise (130 vs. 22), lymphadenopathy (83 vs. 7), asthenia (76 vs. 25), decreased appetite (39 vs. 9), hyperhidrosis (31 vs. 9), lethargy (25 vs. 6), and night sweats (17 vs. 3).

In analyses of all unsolicited adverse events in Study 2 from Dose 1 up to the participant unblinding date, 58.2% of study participants had at least 4 months of follow-up after Dose 2. Among participants 16 through 55 years of age who received at least 1 dose of study vaccine, 12,995 of whom received COMIRNATY and 13,026 of whom received placebo, unsolicited adverse events were reported by 4,396 (33.8%) participants in the COMIRNATY group and 2,136 (16.4%) participants in the placebo group. In a similar analysis in participants 56 years of age and older that included 8,931 COMIRNATY recipients and 8,895 placebo recipients, unsolicited adverse events were reported by 2,551 (28.6%) participants in the COMIRNATY group and 1,432 (16.1%) participants in the placebo group. Among participants with confirmed stable HIV infection that included 100 COMIRNATY recipients and 100 placebo recipients, unsolicited adverse events were reported by 29 (29%) participants in the COMIRNATY group and 15 (15%) participants in the placebo group. The higher frequency of reported unsolicited adverse events among COMIRNATY recipients compared to placebo recipients was primarily attributed to events that are consistent with adverse reactions solicited among participants in the reactogenicity subset (Table 6 and Table 7).

Throughout the placebo-controlled safety follow-up period, Bell's palsy (facial paralysis) was reported by 4 participants in the COMIRNATY group and 2 participants in the placebo group. Onset of facial paralysis was Day 37 after Dose 1 (participant did not receive Dose 2) and Days 3, 9, and 48 after Dose 2. In the placebo group the onset of facial paralysis was Day 32 and Day 102. Currently available information is insufficient to determine a causal relationship with the vaccine. In the analysis of blinded, placebo-controlled follow-up, there were no other notable patterns or numerical imbalances between treatment groups for specific categories of non-serious adverse events (including other neurologic or neuro-inflammatory, and thrombotic events) that would suggest a causal relationship to COMIRNATY. In the analysis of unblinded follow-up, there were no notable patterns of specific categories of non-serious adverse events that would suggest a causal relationship to COMIRNATY.

Serious Adverse Events

Participants 16 through 55 years of age in Study 2 who had received at least 1 dose of vaccine or placebo (COMIRNATY = 12,995; placebo = 13,026), reported serious adverse events from Dose 1 up to the participant unblinding date in ongoing follow-up as follows: 103 (0.8%) COMIRNATY recipients and 117 (0.9%) placebo recipients. In a similar analysis, in participants 56 years of age and older (8,931 COMIRNATY group and 8,895 placebo group), serious adverse events were reported by 165 (1.8%) COMIRNATY recipients and 151 (1.7%) placebo recipients who received at least 1 dose of COMIRNATY or placebo, respectively. In these analyses, 58.2% of study participants had at least 4 months of follow-up after Dose 2. Among participants with confirmed stable HIV infection serious adverse events from Dose 1 up to the participant unblinding date in ongoing follow-up were reported by 2 (2%) COMIRNATY recipients and 2 (2%) placebo recipients.

In the analysis of blinded, placebo-controlled follow-up, there were no notable patterns between treatment groups for specific categories of serious adverse events (including neurologic, neuro-inflammatory, and thrombotic events) that would suggest a causal relationship to COMIRNATY. In the analysis of unblinded follow-up, there were no notable patterns of specific categories of serious adverse events that would suggest a causal relationship to COMIRNATY.

First Booster Dose With COMIRNATY Following the Primary Series

12 Through 15 Years of Age

A subset of 825 Study 2 Phase 2/3 participants 12 through 15 years of age received a booster dose of COMIRNATY 11.2 months (median time, range 6.3 to 20.1 months) after completing the primary series and had a median follow-up time of 9.5 months up to a data cutoff date of November 3, 2022.

Unsolicited Adverse Events

Among participants 12 years of age and older, unsolicited adverse events were reported by 48 (6.6%) participants who received a second booster dose through 1 month after the booster dose. Lymphadenopathy occurred in 7 (1.0%) participants.

6.2 Postmarketing Experience

The following adverse reactions have been identified during postmarketing use of COMIRNATY, Pfizer-BioNTech COVID-19 Vaccine and Pfizer-BioNTech COVID-19 Vaccine, Bivalent. Because these reactions are reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency or establish a causal relationship to vaccine exposure.

Cardiac Disorders: myocarditis, pericarditis
Gastrointestinal Disorders: diarrhea, vomiting
Immune System Disorders: severe allergic reactions, including anaphylaxis, and other hypersensitivity reactions (e.g., rash, pruritus, urticaria, angioedema)
Musculoskeletal and Connective Tissue Disorders: pain in extremity (arm)
Nervous System Disorders: syncope, dizziness

8 USE IN SPECIFIC POPULATIONS

     

8.1 Pregnancy

Risk Summary

All pregnancies have a risk of birth defect, loss, or other adverse outcomes. In the US general population, the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies is 2% to 4% and 15% to 20%, respectively. Available data on COMIRNATY administered to pregnant women are insufficient to inform vaccine-associated risks in pregnancy.

A developmental toxicity study has been performed in female rats administered the equivalent of a single human dose of COMIRNATY [encoding the viral spike (S) glycoprotein of SARS-CoV-2 Wuhan-Hu-1 strain (Original)] on 4 occasions, twice prior to mating and twice during gestation. These studies revealed no evidence of harm to the fetus due to the vaccine (see Animal Data).

Clinical Considerations

Disease-Associated Maternal and/or Embryo/Fetal Risk

Pregnant individuals infected with SARS-CoV-2 are at increased risk of severe COVID-19 compared with non-pregnant individuals.

Data

Animal Data

In a developmental toxicity study, 0.06 mL of a vaccine formulation containing the same quantity of nucleoside-modified messenger ribonucleic acid (mRNA) (30 mcg) and other ingredients included in a single human dose of COMIRNATY [encoding the viral spike (S) glycoprotein of SARS-CoV-2 Wuhan-Hu-1 strain (Original)] was administered to female rats by the intramuscular route on 4 occasions: 21 and 14 days prior to mating, and on gestation days 9 and 20. No vaccine-related adverse effects on female fertility, fetal development, or postnatal development were reported in the study.

8.2 Lactation

Risk Summary

It is not known whether COMIRNATY is excreted in human milk. Data are not available to assess the effects of COMIRNATY on the breastfed infant or on milk production/excretion. The developmental and health benefits of breastfeeding should be considered along with the mother's clinical need for COMIRNATY and any potential adverse effects on the breastfed child from COMIRNATY or from the underlying maternal condition. For preventive vaccines, the underlying maternal condition is susceptibility to disease prevented by the vaccine.

8.4 Pediatric Use

Safety and effectiveness of COMIRNATY in individuals 12 through 17 years of age is based on safety and effectiveness data in this age group and in adults [see Adverse Reactions (6) and Clinical Studies (14.1)].

The safety and effectiveness of COMIRNATY in individuals younger than 12 years of age have not been established. Evidence from clinical studies in individuals 6 months through 4 years of age strongly suggests that a single dose of COMIRNATY would be ineffective in individuals younger than 6 months of age.

8.5 Geriatric Use

Of the total number of COMIRNATY recipients in Study 2 as of March 13, 2021 (N = 22,026), 20.7% (n = 4,552) were 65 years of age and older and 4.2% (n = 925) were 75 years of age and older [see Clinical Studies (14.1)]. In Study 4, of 5081 recipients who received COMIRNATY as the first booster dose, 23.1% (n = 1175) were 65 years of age and older and 5.2% (n = 265) were 75 years of age and older. In Study 5, of 726 recipients who received Pfizer-BioNTech COVID-19 Vaccine, Bivalent as the second booster dose, 21.9% (n = 159) were 65 years of age and older and 4.8% (n = 35) were 75 years of age and older. No overall differences in safety or effectiveness were observed between these recipients and younger recipients.

8.6 Immunocompromised Individuals

The Centers for Disease Control and Prevention has published considerations related to COVID-19 vaccination for individuals who are moderately to severely immunocompromised (https://www.cdc.gov/vaccines/covid-19/clinical-considerations/covid-19-vaccines-us.html).

11 DESCRIPTION

COMIRNATY (COVID-19 Vaccine, mRNA) is a sterile suspension for injection for intramuscular use.

Each 0.3 mL dose of COMIRNATY (2023-2024 Formula) is formulated to contain 30 mcg of a nucleoside-modified messenger RNA (modRNA) encoding the viral spike (S) glycoprotein of SARS-CoV-2 Omicron variant lineage XBB.1.5 (Omicron XBB.1.5).

Each 0.3 mL dose of COMIRNATY also includes the following ingredients: lipids (0.43 mg ((4-hydroxybutyl)azanediyl)bis(hexane-6,1-diyl)bis(2-hexyldecanoate), 0.05 mg 2-(polyethylene glycol 2000)-N,N-ditetradecylacetamide, 0.09 mg 1,2-distearoyl-sn-glycero-3-phosphocholine, and 0.19 mg cholesterol), 0.06 mg tromethamine, 0.4 mg tromethamine hydrochloride, and 31 mg sucrose.

COMIRNATY does not contain preservatives.

The vial stoppers are not made with natural rubber latex.

The prefilled syringe tip cap and plunger stopper are not made with natural rubber latex.

12 CLINICAL PHARMACOLOGY

12.1 Mechanism of Action

The nucleoside-modified mRNA in COMIRNATY is formulated in lipid particles, which enable delivery of the mRNA into host cells to allow expression of the SARS-CoV-2 S antigen. The vaccine elicits an immune response to the S antigen, which protects against COVID-19.

13 NONCLINICAL TOXICOLOGY

13.1 Carcinogenesis, Mutagenesis, Impairment of Fertility

COMIRNATY has not been evaluated for the potential to cause carcinogenicity, genotoxicity, or impairment of male fertility. In a developmental toxicity study in rats with COMIRNATY [encoding the viral spike (S) glycoprotein of SARS-CoV-2 Wuhan-Hu-1 strain (Original)] there were no vaccine-related effects on female fertility [see Use in Specific Populations (8.1)].

14 CLINICAL STUDIES

    

14.1 Immunogenicity Data Supporting the Use of a Single Dose of COMIRNATY in Seropositive, Vaccine-Naïve Individuals

In a post-hoc analysis in a subset of participants 18 through 85 years of age enrolled in Study 7 (NCT05004181), immunogenicity of a single 30 mcg dose of a Pfizer-BioNTech bivalent COVID-19 vaccine containing equal quantities of modRNA encoding the viral spike (S) glycoprotein for the Alpha and Delta SARS-CoV-2 variants [not authorized or approved in the U.S., hereafter referred to as bivalent vaccine (Alpha and Delta)] was assessed in COVID-19 vaccine-naïve participants with evidence of prior SARS-CoV-2 infection (n = 262) compared to participants without prior SARS-CoV-2 infection who received 2 doses of COMIRNATY in Study 2 (n = 275). Among Study 7 participants, 253 were from study sites in South Africa and 9 were from study sites in the U.S. The immunogenicity of the bivalent Alpha and Delta vaccine is relevant to COMIRNATY because these vaccines are manufactured using the same process with differences only in the encoded spike proteins.

Table 10 presents demographic characteristics for participants in the immunogenicity analysis set.

The objective of this analysis was to assess noninferiority with respect to level of 50% neutralizing titer (NT50) and to the seroresponse rate to the reference strain induced by a single dose of the bivalent Alpha and Delta vaccine in COVID-19 vaccine-naïve participants with evidence of prior infection relative to participants without evidence of SARS-CoV-2 infection who received 2 doses of COMIRNATY.

Noninferiority of the reference strain immune response with respect to level of NT50 was met, as the lower bound of the 2-sided 95% CI for the geometric mean ratio (GMR) was >0.67 (Table 11). Noninferiority of the seroresponse rate to the reference strain was not met, as the lower bound of the 2-sided 95% CIs for the difference in seroresponse rate of reference strain was -10.04%, below the noninferiority margin of -10% (Table 12).

14.2 Primary Series With COMIRNATY – Efficacy in Participants 16 Years of Age and Older

Study 2 is an ongoing, multicenter, multinational, randomized, placebo-controlled, observer-blind, dose-finding, vaccine candidate–selection, and efficacy study in participants 12 years of age and older. Randomization was stratified by age: 12 through 15 years of age, 16 through 55 years of age, or 56 years of age and older, with a minimum of 40% of participants in the ≥56-year stratum. The study excluded participants who were immunocompromised and those who had previous clinical or microbiological diagnosis of COVID-19. Participants with preexisting stable disease, defined as disease not requiring significant change in therapy or hospitalization for worsening disease during the 6 weeks before enrollment, were included as were participants with known stable infection with HIV, hepatitis C virus (HCV), or hepatitis B virus (HBV).

In Study 2, based on data accrued through March 13, 2021, approximately 44,000 participants 12 years of age and older were randomized equally and received 2 doses of COMIRNATY or placebo. Participants are planned to be followed for up to 24 months, for assessments of safety and efficacy against COVID-19.

Overall, among the total participants who received COMIRNATY or placebo, 51.4% or 50.3% were male and 48.6% or 49.7% were female, 79.1% or 79.2% were 16 through 64 years of age, 20.9% or 20.8% were 65 years of age and older, 81.9% or 82.1% were White, 9.5% or 9.6% were Black or African American, 1.0% or 0.9% were American Indian or Alaska Native, 4.4% or 4.3% were Asian, 0.3% or 0.2% Native Hawaiian or other Pacific Islander, 25.6% or 25.4% were Hispanic/Latino, 73.9% or 74.1% were non-Hispanic/Latino, 0.5% or 0.5% did not report ethnicity, 46.0% or 45.7% had comorbidities [participants who have 1 or more comorbidities that increase the risk of severe COVID-19 disease: defined as subjects who had at least 1 of the Charlson comorbidity index category or body mass index (BMI) ≥30 kg/m2], respectively. The mean age at vaccination was 49.8 or 49.7 years and median age was 51.0 or 51.0 in participants who received COMIRNATY or placebo, respectively.

Efficacy Against COVID-19

The population for the analysis of the protocol pre-specified primary efficacy endpoint included 36,621 participants 12 years of age and older (18,242 in the COMIRNATY group and 18,379 in the placebo group) who did not have evidence of prior infection with SARS-CoV-2 through 7 days after the second dose. The population in the protocol pre-specified primary efficacy analysis included all participants 12 years of age and older who had been enrolled from July 27, 2020, and followed for the development of COVID-19 through November 14, 2020. Participants 18 through 55 years of age and 56 years of age and older began enrollment from July 27, 2020, 16 through 17 years of age began enrollment from September 16, 2020, and 12 through 15 years of age began enrollment from October 15, 2020.

For participants without evidence of SARS-CoV-2 infection prior to 7 days after Dose 2, vaccine efficacy against confirmed COVID-19 occurring at least 7 days after Dose 2 was 95.0% (95% credible interval: 90.3, 97.6), which met the pre-specified success criterion. The case split was 8 COVID-19 cases in the COMIRNATY group compared to 162 COVID-19 cases in the placebo group.

The population for the updated vaccine efficacy analysis included participants 16 years of age and older who had been enrolled from July 27, 2020, and followed for the development of COVID-19 during blinded placebo-controlled follow-up through March 13, 2021, representing up to 6 months of follow-up after Dose 2. There were 12,796 (60.8%) participants in the COMIRNATY group and 12,449 (58.7%) in the placebo group followed for ≥4 months after Dose 2 in the blinded placebo-controlled follow-up period.

SARS-CoV-2 variants of concern identified from COVID-19 cases for this age group from this data cutoff include B.1.1.7 (Alpha) and B.1.351 (Beta). Representation of identified variants among cases in vaccine versus placebo recipients did not suggest decreased vaccine effectiveness against these variants.

The updated vaccine efficacy information is presented in Table 13.

Efficacy Against Severe COVID-19

Efficacy analyses of secondary efficacy endpoints supported the benefit of COMIRNATY in preventing severe COVID-19. Vaccine efficacy against severe COVID-19 is presented only for participants with or without prior SARS-CoV-2 infection (Table 14) as the COVID-19 case counts in participants without prior SARS-CoV-2 infection were the same as those in participants with or without prior SARS-CoV-2 infection in both the COMIRNATY and placebo groups.

14.4 Booster Dose With COMIRNATY – Immunogenicity of a First Booster Dose in Individuals 18 Through 55 Years of Age

Effectiveness of a booster dose of COMIRNATY was based on an assessment of 50% neutralizing antibody titers (NT50) against SARS-CoV-2 reference strain (USA_WA1/2020) in Study 2 participants 18 through 55 years of age (n = 200 – 212) who had no serological or virological evidence of past SARS‑CoV‑2 infection up to 1 month after the booster vaccination. Analyses of NT50 1 month after the booster dose compared to 1 month after the primary series demonstrated noninferiority for both geometric mean ratio (GMR) [3.26 (97.5% CI: 2.76, 3.86)] and difference in seroresponse rates (percentage) [4.5% (97.5% CI: 1.0, 7.9)]. Seroresponse for a participant was defined as achieving a ≥4-fold rise in NT50 from baseline (before primary series).

14.5 Booster Dose With Pfizer-BioNTech COVID-19 Vaccine, Bivalent – Immunogenicity of a Second Booster Dose in Individuals 12 Years of Age and Older

In an analysis of a subset from Study 5, 105 participants 12 through 17 years of age, 297 participants 18 through 55 years of age, and 286 participants 56 years of age and older who had previously received a 2-dose primary series and 1 booster dose with COMIRNATY received a second booster dose of Pfizer-BioNTech COVID-19 Vaccine, Bivalent. In participants 12 through 17 years of age, 18 through 55 years of age, and 56 years of age and older, 75.2%, 71.7% and 61.5% were positive for SARS-CoV-2 at baseline, respectively.

Analyses of NT50 against Omicron BA.4/BA.5 and against reference strain among participants 56 years of age and older who received a second booster dose of Pfizer-BioNTech COVID-19 Vaccine, Bivalent in Study 5 compared to a subset of participants from Study 4 who received a second booster dose of COMIRNATY demonstrated superiority of Pfizer-BioNTech COVID-19 Vaccine, Bivalent to COMIRNATY based on GMR and noninferiority based on difference in seroresponse rates with respect to anti-Omicron BA.4/BA.5 response, and noninferiority of anti-reference strain immune response based on GMR (Table 17 and Table 18).

Analyses of NT50 against Omicron BA.4/BA.5 among participants 18 through 55 years of age compared to participants 56 years of age and older who received a second booster dose of Pfizer-BioNTech COVID-19 Vaccine, Bivalent in Study 5 demonstrated noninferiority of anti-Omicron BA.4/BA.5 response among participants 18 through 55 years of age to participants 56 years of age and older for both GMR and difference in seroresponse rates (Table 17 and Table 18).

The study also assessed the level of NT50 against the anti-Omicron BA.4/BA.5 and original SARS-CoV-2 strains pre-vaccination and 1 month after vaccination in participants who received a second booster dose (Table 19).

Regardless of presentation, during storage, minimize exposure to room light, and avoid exposure to direct sunlight and ultraviolet light.

Regardless of storage condition, the vaccine should not be used after the expiration date printed on the vials, prefilled syringes, and cartons.

Storage Prior to Use

Glass Prefilled Syringes (NDC 0069-2377)

COMIRNATY glass prefilled syringes (NDC 0069-2377) may be stored at 2°C to 8°C (35°F to 46°F) until the expiration date printed on the carton and syringe labels. DO NOT FREEZE.

The total time out of refrigeration (at temperatures between 8°C and 25°C (46°F and 77°F)) must not exceed 12 hours.

Plastic Prefilled Syringes (NDC 0069-2392) and Single Dose Vials (NDC 0069-2362)

COMIRNATY plastic prefilled syringes (NDC 0069-2392) and single dose vials (NDC 0069-2362) may arrive frozen at ultra-cold conditions in thermal containers with dry ice. Once received, frozen plastic prefilled syringes and vials may be immediately transferred to the refrigerator at 2ºC to 8ºC (35ºF to 46ºF), thawed and stored for up to 10 weeks. The 10-week refrigerated expiry date should be recorded on the carton at the time of transfer. Cartons of 10 single dose plastic prefilled syringes or cartons of 10 single dose vials may take up to 2 hours to thaw at this temperature. Once thawed, they should not be refrozen.

Alternatively, frozen plastic prefilled syringes and single dose vials may be stored in an ultra-low temperature freezer at -90ºC to -60ºC (-130ºF to -76ºF). Do not store vials and prefilled syringes at -25°C to -15°C (-13°F to 5°F).

Cartons of COMIRNATY plastic prefilled syringes and single dose vials may be received at 2°C to 8°C (35ºF to 46ºF), and they should be stored at 2°C to 8°C (35ºF to 46ºF). Check that the carton has been previously updated to reflect the 10-week refrigerated expiry date.

The total time out of refrigeration (at temperatures between 8°C and 25°C (46°F and 77°F)) must not exceed 12 hours.

Storage During Use

Storage of Glass Prefilled Syringes

After removing the tip cap and attaching an appropriate needle, the glass prefilled syringe should be used immediately. If it cannot be used immediately, it must be used within 4 hours.

Thawing and Storage of Plastic Prefilled Syringes

Frozen COMIRNATY plastic prefilled syringes should be thawed in the carton, preferably at 2ºC to 8ºC (35ºF to 46ºF) for 2 hours. A full carton of plastic prefilled syringes may also be thawed at room temperature [up to 25ºC (77ºF)] for 60 minutes. Plastic prefilled syringes thawed in the carton by either method may be stored in the refrigerator for 10 weeks. If individual frozen plastic prefilled syringes are thawed at room temperature outside of the carton, they can be kept at room temperature and must be used within 4 hours of thawing.

After removing the tip cap and attaching an appropriate needle, the plastic prefilled syringe should be used immediately. If it cannot be used immediately, it must be used within 4 hours.

Thawing and Storage of Single Dose Vials

If not previously thawed at 2ºC to 8ºC (35ºF to 46ºF), allow COMIRNATY single dose vials to thaw at room temperature [up to 25ºC (77ºF)] for 30 minutes.

Thawed COMIRNATY single dose vials may be stored at 8°C to 25°C (46°F to 77°F) for a total of 12 hours.

Transportation of Single Dose Vials and Prefilled Syringes

If local redistribution is needed, glass prefilled syringes (NDC 0069-2377) may be transported at 2°C to 8°C (35°F to 46°F) and should never be frozen.

Plastic prefilled syringes (NDC 0069-2392) and single dose vials (NDC 0069-2362) may be transported at −90°C to −60°C (−130°F to −76°F), or at 2°C to 8°C (35°F to 46°F). Plastic prefilled syringes (NDC 0069-2392) should only be transported at −90°C to −60°C if the cartons are sealed in the original aluminum shipping pouches.

Patient Package Insert

*
COMIRNATY (2023-2024 Formula) is made the same way as Pfizer-BioNTech COVID-19 Vaccine (Original monovalent) and Pfizer-BioNTech COVID-19 Vaccine, Bivalent, but it encodes the spike protein of SARS-CoV-2 Omicron variant lineage XBB.1.5 (Omicron XBB.1.5).

INFORMATION FOR RECIPIENTS AND CAREGIVERS

COMIRNATY (Cuh-mir'-na-tee)

(COVID-19 VACCINE, mRNA)

(2023-2024 Formula)

This summary is not intended to take the place of talking with your healthcare provider. If you have questions or would like more information, please talk with your healthcare provider.

What is COMIRNATY?

COMIRNATY is a vaccine for use in people 12 years of age and older to protect against COVID-19.

COMIRNATY may not protect all people who receive the vaccine.

COMIRNATY does not contain SARS-CoV-2, the virus that causes COVID-19. COMIRNATY cannot give you COVID-19.

Who should not get COMIRNATY?

You should not get COMIRNATY if you had:

a severe allergic reaction after a previous dose of COMIRNATY or any Pfizer-BioNTech COVID-19 vaccine*
a severe allergic reaction to any ingredient in these vaccines (see What are the ingredients in COMIRNATY?).

Before getting COMIRNATY, tell your vaccination provider about all of your medical conditions, including if you:

have any allergies
had a severe allergic reaction after receiving a previous dose of any COVID-19 vaccine
have had myocarditis (inflammation of the heart muscle) or pericarditis (inflammation of the lining outside the heart)
have a fever
have a bleeding disorder or are on a blood thinner
are immunocompromised or are on a medicine that affects your immune system
are pregnant or plan to become pregnant
are breastfeeding
have received another COVID-19 vaccine
have ever fainted in association with an injection

How is COMIRNATY given?

COMIRNATY is given as an injection into the muscle.

What are the possible risks of COMIRNATY?

There is a remote chance that COMIRNATY could cause a severe allergic reaction. A severe allergic reaction would usually occur within a few minutes to 1 hour after getting a dose. For this reason, your vaccination provider may ask you to stay at the place where you received your vaccine for monitoring after vaccination. Signs of a severe allergic reaction can include:

Difficulty breathing
Swelling of your face and throat
A fast heartbeat
A bad rash all over your body
Dizziness and weakness

Myocarditis (inflammation of the heart muscle) and pericarditis (inflammation of the lining outside the heart) have occurred in some people who have received mRNA COVID-19 vaccines, including COMIRNATY and Pfizer-BioNTech COVID-19 vaccines. Myocarditis and pericarditis following COMIRNATY have occurred most commonly in adolescent males 12 through 17 years of age. In most of these individuals, symptoms began within a few days following vaccination. The chance of having this occur is very low. You should seek medical attention right away if you or your child have any of the following symptoms after receiving the vaccine, particularly during the 2 weeks after receiving a dose of the vaccine:

Chest pain
Shortness of breath
Feelings of having a fast-beating, fluttering, or pounding heart

Side effects that have been reported with COMIRNATY or Pfizer-BioNTech COVID-19 vaccines include:

Severe allergic reactions
Non-severe allergic reactions such as rash, itching, hives, or swelling of the face
Myocarditis (inflammation of the heart muscle)
Pericarditis (inflammation of the lining outside the heart)
Injection site reactions: pain, swelling, redness, arm pain
General side effects: tiredness, headache, muscle pain, chills, joint pain, fever, nausea, feeling unwell, swollen lymph nodes (lymphadenopathy), decreased appetite, diarrhea, vomiting, dizziness
Fainting in association with injection of the vaccine

These may not be all the possible side effects of COMIRNATY. Ask your healthcare provider about any side effects that concern you.

Report vaccine side effects to FDA/CDC Vaccine Adverse Event Reporting System (VAERS). The VAERS toll-free number is 1-800-822-7967 or report online to https://vaers.hhs.gov/reportevent.html.

In addition, you can report side effects to Pfizer Inc. at 1-800-438-1985 or www.pfizersafetyreporting.com.
