FDA-CBER-2022-5812-0500372
 
6 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 demonstrate increased risks of myocarditis and pericarditis, particularly within 7 days following the second dose. The observed risk is higher among males under 40 years of age than among females 
and older males. 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 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 the COMIRNATY.  5.5
 Limitation of Effectiveness 
 COMIRNATY may not protect all vaccine recipients. 
 
6 ADVERSE REACTIONS  
In clinical studies, the most commonly reported ( ≥10%) adverse reactions in participants 16 through 55 years of 
age following any dose were pain at the injection site (88.6%), fatigue (70.1%), headache (64.9%), muscle pain 
(45.5%), chills (41.5%), joint pain (27.5%), fever (17.8%), and injection site swelling (10.6%).  
In clinical studies, the most commonly reported ( ≥10%) adverse reactions in participants 56 years of age and 
older following any dose were pain at the injection site (78.2%), fatigue (56.9%), headache, (45.9%), muscle 
pain (32.5%), chills (24.8%), joint pain (21.5%), injection site swelling (11.8%), fever (11.5%), and injection site redness (10.4%).  
In a clinical study, the most commonly reported ( ≥8%) adverse reactions in adolescents 12 through 15 years of 
age following any dose were pain at the injection site (90.5%), fatigue (77.5%), headache (75.5%), chills 
(49.2%), muscle pain (42.2%), fever (24.3%), joint pain (20.2%), injection site swelling (9.2%), and injection site redness (8.6%). 
 
FDA-CBER-2022-5812-0500373
 
7 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. 
 
The safety 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 C4591001 
(Study 2) is a Phase 1/2/3 multicenter, multinational, randomized, saline placebo-controlled, double-blinded 
(Phase 2/3), dose-finding, vaccine candidate-selection and efficacy study that has enrolled approximately 
46,000 participants 12 years of age or older. Of these, approximately 44,047 participants 
(22,026 COMIRNATY; 22,021 placebo) in Phase 2/3 are 16 years of age or older (including 378 and 
376 participants 16 through 17 years of age in the COMIRNATY and placebo groups, respectively) and 
2,260 adolescents are 12 through 15 years of age (1,131 and 1,129 in the COMIRNATY and placebo groups, 
respectively). Upon issuance of the Emergency Use Authorization for COMIRNATY, participants were 
unblinded to offer placebo participants COMIRNATY. Participants were unblinded in a phased manner over a period of months to offer placebo participants COMIRNATY. Study 2 also included 200 participants with confirmed stable human immunodeficiency virus (HIV) infection; HIV-positive participants are included in 
safety population disposition but are summarized separately in safety analyses. Confirmed stable HIV infection 
was defined as documented viral load <50 copies/mL and CD4 count >200 cells/mm
3 within 6 months before 
enrollment, and on stable antiretroviral therapy for at least 6 months.  In Study 2, all participants 12 through 15 years of age, and 16 years and older in the reactogenicity subset were 
monitored for solicited local and systemic reactions and use of antipyretic medication after each vaccination in 
an electronic diary. Participants are being monitored for unsolicited adverse events, including serious adverse events, throughout the study [from Dose 1 through 1 month (all unsolicited adverse events) or 6 months (serious adverse events) after the last vaccination]. Tables 1 through 6 present the frequency and severity of solicited 
local and systemic reactions, respectively, within 7 days following each dose of COMIRNATY and placebo. 
 
Participants 16 Years of Age and Older 
 
At the time of the analysis of the ongoing Study 2 with a data cut-off of March 13, 2021, there were 
25,651 (58.2%) participants (13,031 COMIRNATY and 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 
FDA-CBER-2022-5812-0500374
 
8 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

Unsolicited Adverse Events 
 
Overall, 11,253 (51.1%) participants 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 one 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 
FDA-CBER-2022-5812-0500379
 
13 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 3 and Table 4). 
 
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 
In Study 2, among participants 16 through 55 years of age who had received at least 1 dose of vaccine or 
placebo (COMIRNATY =12,995; placebo = 13,026), serious adverse events from Dose 1 up to the participant 
unblinding date in ongoing follow-up were reported by 103 (0.8%) COMIRNATY recipients and 117 (0.9%) 
placebo recipients. In a similar analysis, in participants 56 years of age and older (COMIRNATY = 8,931; 
placebo = 8,895), 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. 
 
Adolescents 12 Through 15 Years of Age  
 
In an analysis of long term safety follow up in Study 2, 2,260 adolescents (1,131 COMIRNATY; 
1,129 placebo) were 12 through 15 years of age.  Of these At the time of the analysis of the ongoing Study 2 
with a data cutoff of September 2, 2021 , there were 1,559 (70.7%) adolescents  (786 COMIRNATY and 773 
placebo) 12 through 15 years of ageadolescents have been  followed for ≥4 months after the second dose. The 
safety evaluation in Study 2 is ongoing.  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 an analysis of all unsolicited adverse events reported following any dose, through 1 month after Dose 2, in 
adolescents 12 to 15 years of age and older (N=2260; 1,131 COMIRNATY group vs. 1,129 placebo group), 
those assessed as adverse reactions not already captured by solicited local and systemic reactions were 
lymphadenopathy (9 vs. 2), and nausea (5 vs. 1).  
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.   
 
AIn n analys ies of all unsolicited adverse events in Study 2 from Dose 1 up to the participant unblinding date  
was conducted. , 69.0% of study participants 12 through 15 years of age had at least 4 months of follow-up after 
Dose 2 (N=2260; 1,131 COMIRNATY group vs. 1,129 placebo group). Among participants 12 through 
15 years of age who received at least one dose of study vaccine, 1,131 of whom received COMIRNATY and 
1,129 of whom received placebo, 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 fromfollowing any dose, 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. 1).  
 
Non serious adverse events from Dose 1 through up to 30 days after Dose 2 in ongoing follow up were reported 
by 5.8% of COMIRNATY recipients and by 5.8% of placebo recipients. From Dose 1 through 30 days after 
Dose 2, reports of lymphadenopathy plausibly related to the study intervention were imbalanced, with notably 
more cases in the COMIRNATY group (7) vs. the placebo group (1). 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-seriousunsolicited  adverse events (including other neurologic or neuro-
inflammatory, and thrombotic events) that would suggest a causal relationship to COMIRNATY. In the analysis 
FDA-CBER-2022-5812-0500383
 
17 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. 
 
6.2 Postmarketing Experience  
 
The following adverse reactions have been identified during postmarketing use of COMIRNATY, including 
under Emergency Use Authorization. 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) 
 
8 USE IN SPECIFIC POPULATIONS 
 
8.1 Pregnancy 
 There is a pregnancy exposure registry that monitors pregnancy outcomes in women exposed to COMIRNATY during pregnancy. Women who are vaccinated with COMIRNATY during pregnancy are encouraged to enroll in the registry by visiting https://mothertobaby.org/ongoing-study/covid19-vaccines/ . 
 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 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) . 
 
FDA-CBER-2022-5812-0500384
 
18 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 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. 
 
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)] . No overall differences in safety or effectiveness were observed between these 
recipients and younger recipients. 
 
11 DESCRIPTION  
 COMIRNATY (COVID-19 Vaccine, mRNA) is a sterile suspension for injection for intramuscular use. 
COMIRNATY is supplied as a frozen suspension in multiple dose vials; each vial must be diluted with 1.8 mL 
of sterile 0.9% Sodium Chloride Injection, USP prior to use to form the vaccine. Each dose of COMIRNATY contains 30 mcg of a nucleoside-modified messenger RNA (mRNA) encoding the viral spike (S) glycoprotein of SARS-CoV-2.   
Each 0.3 mL dose of the 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-( ω-methoxy-(Pp olyethylene 
glycol )- 2000)-N,N-ditetradecylacetamide, 0.09 mg 1,2-distearoyl-sn-glycero-3-phosphocholine, and 0.2 mg 
cholesterol), 0.01 mg potassium chloride, 0.01 mg monobasic potassium phosphate, 0.36 mg sodium chloride, 
0.07 mg dibasic sodium phosphate dihydrate, and 6 mg sucrose. The diluent (0.9% Sodium Chloride Injection, 
USP) contributes an additional 2.16 mg sodium chloride per dose.  
FDA-CBER-2022-5812-0500385
 
19 COMIRNATY does not contain preservative.  
 The vial stoppers 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 there were no vaccine-related 
effects on female fertility [see Use in Specific Populations (8.1)] . 
 
14 CLINICAL STUDIES 
 
14.1 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 COVID19. 
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 one of the 
Charlson comorbidity index category or body mass index (BMI) ≥30 kg/m
2], 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.  
 
FDA-CBER-2022-5812-0500386
 
20 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 COVID19 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 cutoffin 
this study  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.

Subgroup analyses of vaccine efficacy (although limited by small numbers of cases in some subgroups) did not 
suggest meaningful differences in efficacy across genders, ethnic groups, geographies, or for participants with 
obesity or medical comorbidities associated with high risk of severe COVID-19. 
 
Efficacy Against Severe COVID-19 
 Efficacy analyses of secondary efficacy endpoints supported 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 8) 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.

FDA-CBER-2022-5812-0500391
 
25 Frozen Vials Prior to Use 
 
Cartons of COMIRNATY Multiple Dose Vials arrive in thermal containers with dry ice. Once received, remove 
the vial cartons immediately from the thermal container and preferably store in an ultra-low temperature freezer 
between -90ºC to -60ºC (-130ºF to -76ºF) until the expiry date printed on the label. Alternatively, vials may be stored at -25°C to -15°C (-13°F to 5°F) for up to 2 weeks. Vials must be kept frozen and protected from light, in the original cartons, until ready to use. Vials stored at -25°C to -15°C (-13°F to 5°F) for up to 2 weeks may be 
returned 1 time to the recommended storage condition of -90ºC to -60ºC (-130ºF to -76ºF). Total cumulative 
time the vials are stored at -25°C to -15°C (-13°F to 5°F) should be tracked and should not exceed 2 weeks. 
 
If an ultra-low temperature freezer is not available, the thermal container in which COMIRNATY arrives may 
be used as temporary storage when consistently re-filled to the top of the container with dry ice. Refer to the 
re-icing guidelines packed in the original thermal container for instructions regarding the use of the thermal 
container for temporary storage. The thermal container maintains a temperature range of -90ºC to -60ºC (-130ºF 
to -76ºF). Storage of the vials between -96°C to -60°C (-141°F to -76°F) is not considered an excursion from the recommended storage condition.  
 Transportation of Frozen Vials 
 If local redistribution is needed and full cartons containing vials cannot be transported at -90°C to -60°C 
(-130°F to -76°F), vials may be transported at -25°C to -15°C (-13°F to 5°F). Any hours used for transport 
at -25°C to -15°C (-13°F to 5°F) count against the 2-week limit for storage at -25°C to -15°C (-13°F to 5°F). Frozen vials transported at -25°C to -15°C (-13°F to 5°F) may be returned 1 time to the recommended storage condition of -90ºC to -60ºC (-130ºF to -76ºF). 
 
Thawed Vials Before Dilution 
 Thawed Under Refrigeration  
Thaw and then store undiluted vials in the refrigerator [2ºC to 8ºC (35ºF to 46ºF)] for up to 1 month. A carton of 
25 vials or 195 vials may take up to 2 or 3 hours, respectively, to thaw in the refrigerator, whereas a fewer number of vials will thaw in less time.   
Thawed at Room Temperature 
 For immediate use, thaw undiluted vials at room temperature [up to 25ºC (77ºF)] for 30 minutes. Thawed vials can be handled in room light conditions.  
 
Vials must reach room temperature before dilution.  Undiluted vials may be stored at room temperature for no more than 2 hours.  
Transportation of Thawed Vials 
 
Available data support transportation of 1 or more thawed vials at 2°C to 8°C (35°F to 46°F) for up to 12 hours.   
FDA-CBER-2022-5812-0500392
 
26 Vials After Dilution 
 
After dilution, store vials between 2°C to 25°C (35°F to 77°F) and use within 6 hours from the time of dilution. 
During storage, minimize exposure to room light, and avoid exposure to direct sunlight and ultraviolet light. Any vaccine remaining in vials must be discarded after 6 hours. Do not refreeze.
