3 THAWING PRIOR TO DILUTION
• Thaw vial(s) of COMIRNATY before dilution either
by:
o Allowing vial(s) to thaw in the refrigerator [2ºC
to 8ºC (35ºF to 46ºF)]. A carton of vials may take up to 3 hours to thaw, and thawed vials can be stored in the refrigerator for up to 1 month.
o Allowing vial(s) to sit at room temperature [up to 25ºC (77ºF)] for 30 minutes.
• Using either thawing method, vials must reach room temperature before dilution and must be diluted
within 2 hours.
• Before dilution invert vaccine vial gently 10 times.
• Do not shake.
• Inspect the liquid in the vaccine vial prior to dilution. The liquid is a white to off- white
suspension and may contain white to off- white
opaque amorphous particles.
• Do not use if liquid is discolored or if other particles are observed.
DILUTION
• ONLY use sterile 0.9% Sodium Chloride Injection, USP as the diluent.
• Withdraw 1.8 mL of diluent into a transfer syringe
(21-gauge or narrower needle).
• Add 1.8 mL of sterile 0.9% Sodium Chloride
Injection, USP into the vaccine vial .
FDA-CBER-2022-5812-0220521
FDA-CBER-2022-5812-0220522
5 PREPARATION OF INDIVIDUAL 0.3 mL DOSES OF COMIRNATY
• Withdraw 0.3 mL of COMIRNATY preferentially
using low dead-volume syringes and/or needles.
• Each dose must contain 0.3 mL of vaccine.
• If the amount of vaccine remaining in a single vial
cannot provide a full dose of 0.3 mL, discard the
vial and any excess volume.
• Administer immediately.
After dilution, vials of COMIRNATY contain 6 doses of 0.3 mL of vaccine. Low dead -volume syringes and/or
needles can be used to extract 6 doses from a single vial. If standard syringes and needles are used, there may not be sufficient volume to extract a sixth dose from a single vial. Irrespective of the type of syringe and needle,
• each dose must contain 0.3 mL of vaccine.
• if the amount of vaccine remaining in the vial cannot provide a full dose of 0.3 mL, discard the vial and
any excess volume.
• do not pool excess vaccine from multiple vials.
2.2 Administration Information
Parenteral drug products should be inspected visually for particulate matter and discoloration prior to administration, whenever solution and container permit. The vaccine will be an off -white suspension. Do not
administer if vaccine is discolored or contains particulate matter.
Administer a single 0.3 mL dose of COMIRNATY intramuscularly. 2.3 Vaccination Schedule
COMIRNATY is administered intramuscularly as a series of 2 doses (0.3 mL each) 3 weeks apart.
There are no data available on the interchangeability of COMIRNATY with other COVID -19 vaccines to complete
the vaccination series. Individuals who have received 1 dose of COMIRNATY should receive a second dose of
COMIRNATY to complete the vaccination series.
3 DOSAGE FORMS AND STRENGTHS
COMIRNATY is a suspension for injection. After preparation, 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 the COMIRNATY [s ee Description (1 1)].
FDA-CBER-2022-5812-0220523
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, a vailable 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.

FDA-CBER-2022-5812-0220524
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 16 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
44,04746,000 participants (22,026 COMIRNATY ; 22,021 placebo) 16 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 vaccineCOMIRNATY and placebo
groups, respectively) and 2,260 adolescents are 12 t hrough 15 years of age ( 1,131 and 1,129 in the
COMIRNATY and placebo groups, respectively) . Upon issuance of the Emergency Use Authorization
(December 11, 2020) 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.
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 .
In Study 2, all participants 12 through 15 years of age, and Participants 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 p lacebo , 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.

8 Local and Systemic Adverse Reactions Solicited in the Study 2
Table 1 and Table 2 present the frequency and severity of report ed solicited local and systemic reactions,
respectively, within 7 days following each dose of COMIRNATY and placebo in the subset of participants
16 through 55 years of age included in the safety population who were monitored for reactogenicity with an
electronic diary.
Table 3 and Table 4 present the frequency and severity of reported solicited local and systemic reactions,
respectively, within 7 days of each dose of COMIRNATY and placebo for participants 56 years of age and
older.
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.

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 pla cebo group. In a similar analysis in
FDA-CBER-2022-5812-0220530
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 an d 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 amon g
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, t here
were no other notable patterns or numerical imbalances between treatment groups for specific categori es 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, t here 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 Thr ough 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 t hrough 15 years of age. Of these, 1559 (786 COMIRNATY and 773 placebo)
adolescents 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 N ative .

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 analyses of all unsolicited adverse events in Study 2 from Dose 1 up to the participant unblinding date,
69.0% of study participants 12 through 15 years of age had at least 4 months of follow-up after Dose 2. 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.
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, t here 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 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, t here 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.

17 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 stud y 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) .
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
FDA-CBER-2022-5812-0220535
18 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 preve nted by the vaccine.
8.4 Pediatric Use
Safety and effectiveness of COMIRNATY in individuals 16 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 16 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-(polyethylene
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.
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 m RNA in COMIRNATY is formulated in lipid particles, which enable delivery of the

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 t here 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 a n 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.
Particip ants 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, he patitis C virus (HCV), or hepatitis B virus (HBV).
In Study 2, based on data accrued through March 13, 2021, approximately 44,000 participants 1612 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 r eceived 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, 2 5.6% or 2 5.4% 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 4 9.8 or 4 9.7 years and median age was 5 1.0 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,
FDA-CBER-2022-5812-0220537
20 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 in 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.
The updated vaccine efficacy information is presented in Table 57.

Efficacy Against S evere 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 68) 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.

14.3 Immunogenicity in Adolescents 12 Through 15 Years of Age
In Study 2, an analysis of SARS-CoV-2 50% neutralizing titers (NT50) 1 month after Dose 2 in a randomly
selected subset of participants demonstrated non-inferior immune responses (within 1.5- fold) comparing
adolescents 12 through 15 years of age to participants 16 through 25 years of age who had no serological or
virological evidence of past SARS-CoV-2 infection up to 1 month after Dose 2 (Table 10).

temperature 20 °C to 25°C (68°F to 77°F) [see USP Controlled Room Temperature]. The provided 0.9% Sodium
Chloride Injection, USP diluent will be supplied either as cartons of 10 mL single- use vial s manufactured by
Hospira, Inc (NDC 0409-4888-10), or 2 mL single- use vial s manufactured by Fresenius Kabi USA, LLC
(NDC 63323-186-02).
FDA-CBER-2022-5812-0220541
24
After dilution, 1 vial contains 6 doses of 0.3 mL.
During storage, minimize exposure to room light, and avoid exposure to direct sunlight and ultraviolet light. Do not refreeze thawed vials.
Frozen Vials Prior to Use
Cartons of COMIRNATY Multiple Dose Vials arrive in thermal containers with dry ice. Once received, remove the vial cartons i mmediately 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.
FDA-CBER-2022-5812-0220542
25 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.
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.
