There are no data available on the interchangeability of COMIRN ATY with COVID-19 vaccines from other 
manufacturers to complete the vaccination series. Individuals w ho 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, eac h dose of COMIRNATY supplied in vials 
with purple caps and labels with purple borders is 0.3 mL. 
 
4 CONTRAINDICATIONS 
 Do not administer COMIRNATY to individuals with known history o f a severe allergic reaction (e.g., 
anaphylaxis) to any component of the COMIRNATY  [see Description (11)] . 
 
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 admin istration of COMIRNATY.  
 5.2 Myocarditis and Pericarditis 
 
Postmarketing data demonstrate increased risks of myocarditis a nd pericarditis, particularly within 7 days 
following the second dose. The observed risk is higher among ma les 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. Informatio n 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/m yocarditis.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 f ainting. 
 
5.4 Altered Immunocompetence 
 Immunocompromised persons, including individuals receiving immu nosuppressant therapy, may have a 
diminished immune response to the COMIRNATY.  
FDA-CBER-2022-5812-0235954
 
8 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 sit e swelling (11.8%), fever (11.5%), and injection 
site redness (10.4%). 
 
In a clinical study, the most commonly reported (≥8%) adverse r eactions 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%).  
6.1 Clinical Trials Experience 
 
Because clinical trials are conducted under widely varying cond itions, adverse reaction rates observed in the 
clinical trials of a vaccine cannot be directly compared to rat es 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, Brazi l, Turkey, South Africa, and Germany 
(Study 2). Study BNT162-01 (Study 1) was a Phase 1/2, 2-part, d ose-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, randomiz ed, 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, approxi mately 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 an d placebo groups, respectively) and 
2,260 adolescents are 12 through 15 years of age (1,131 and 1,1 29 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 coun t >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 unsol icited 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 follo wing 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 cutoff of March 13, 2021, there were 
25,651 (58.2%) participants (13,031 COMIRNATY and 12,620 placeb o) 16 years of age and older followed for 
≥4 months after the second dose. 
 
Demographic characteristics in Study 2 were generally similar w ith regard to age, gender, race, and ethnicity 
among participants who received COMIRNATY and those who receive d placebo. Overall, among the total 
participants who received either  COMIRNATY or placebo, 50.9% we re male, 49.1% were female, 79.3% were 
16 through 64 years of age, 20.7% were 65 years of age and olde r, 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 participant s 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.

14 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 follo wing any dose, through 1 month after Dose 2, in 
participants 16 years of age and older (N=43,847; 21,926 COMIRN ATY 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 D ose 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 wer e reported by 4,396 (33.8%) participants in 
the COMIRNATY group and 2,136 (16.4%) participants in the place bo group. In a similar analysis in 
participants 56 years of age and older that included 8,931 COMI RNATY 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 part icipants with confirmed stable HIV infection 
that included 100 COMIRNATY recipients and 100 placebo recipien ts, 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 amo ng 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. Cur rently available information is insufficient to 
determine a causal relationship with the vaccine. In the analys is 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 analys is 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 h ad 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 y ears 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 
FDA-CBER-2022-5812-0235961
 
15 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 (inclu ding 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 categorie s of serious adverse events that would suggest a 
causal relationship to 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. The safety evaluation in Study 2 is ongoing. 
 Demographic characteristics in Study 2 were generally similar w ith 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% w ere 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.

18 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 w ould suggest a causal relationship to 
COMIRNATY. In the analysis of unblinded follow-up, there were n o notable patterns of specific categories of 
non-serious adverse events that would suggest a causal relation ship to COMIRNATY. 
 
Serious Adverse Events  
In Study 2, among participants 12 through 15 years of age who h ad received at least 1 dose of vaccine or 
placebo (COMIRNATY = 1,131; placebo = 1,129), serious adverse e vents 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-u p, there were no notable patterns between 
treatment groups for specific categories of serious adverse eve nts (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 categorie s of serious adverse events that would suggest a 
causal relationship to COMIRNATY. 
 
6.2 Postmarketing Experience  
 
The following adverse reactions have been identified during pos tmarketing 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 extrem ity (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 durin g 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 adv erse outcomes. In the US general population, the 
estimated background risk of major birth defects and miscarriag e in clinically recognized pregnancies is 2% to 
4% and 15% to 20%, respectively. Available data on COMIRNATY ad ministered to pregnant women are 
insufficient to inform vaccine-associated risks in pregnancy.  
 A developmental toxicity study has been performed in female rat s administered the equivalent of a single 
human dose of COMIRNATY on 4 occasions, twice prior to mating a nd twice during gestation. These studies 
revealed no evidence of harm to the fetus due to the vaccine (see Animal Data) . 
 
FDA-CBER-2022-5812-0235965
 
19 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 rep orted 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 c linical 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 s usceptibility 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 younge r 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 Ma rch 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 observ ed between these 
recipients and younger recipients.

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 lipi d particles, which enable delivery of the 
mRNA into host cells to allow expression of the SARS-CoV-2 S an tigen. 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 car cinogenicity, 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 ye ars of age, or 56 years of age and older, with a 
minimum of 40% of participants in the ≥56-year stratum. The stu dy excluded participants who were 
immunocompromised and those who had previous  clinical or microbiological diagnosis of COVID-19. 
Participants with preexisting stable disease, defined as diseas e 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, appro ximately 44,000 participants 12 years of age 
and older were randomized equally and received 2 doses of COMIR NATY or placebo. Participants are planned 
to be followed for up to 24 months, for assessments of safety a nd 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 y ears 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) ≥3 0 kg/m
2], respectively. The mean age at 
vaccination was 49.8 or 49.7 years and median age was 51.0 or 5 1.0 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 CO MIRNATY group and 18,379 in the placebo 
group) who did not have evidence of prior infection with SARS-C oV-2 through 7 days after the second dose. 
The population in the protocol pre-specified primary efficacy a nalysis included all participants 12 years of age 
and older who had been enrolled from July 27, 2020, and followe d 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 g roup.  
 The population for the updated vaccine efficacy analysis includ ed participants 16 years of age and older who 
had been enrolled from July 27, 2020, and followed for the deve lopment of COVID-19 during blinded 
placebo-controlled follow-up through March 13, 2021, representi ng up to 6 months of follow-up after Dose 2. 
There were 12,796 (60.8%) participants in the COMIRNATY group a nd 12,449 (58.7%) in the placebo group 
followed for ≥4 months after Dose 2 in the blinded placebo-cont rolled follow-up period.  
 SARS-CoV-2 variants of concern identified from COVID-19 cases f or 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 ve rsus 
placebo recipients did not suggest decreased vaccine effectiven ess against these variants.

16 HOW SUPPLIED/STORAGE AND HANDLING  
 
COMIRNATY Suspension for Intramuscular Injection, multiple dose  vials with purple caps and labels with 
purple borders are supplied in a carton containing 25 multiple dose vials (NDC 0069-1000-03) or 195 multiple 
dose vials (NDC 0069-1000-02). A 0.9% Sodium Chloride Injection , USP diluent is provided but shipped 
separately, and should be stored at controlled room 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 vials manufactured by Hospira, Inc (NDC 0409-4888-10), or 2 mL single-use vials manufactured by Fresenius Kabi USA, LLC (NDC 63323-18 6-02). 
 
After dilution, 1 vial contains 6 doses of 0.3 mL.  
 
During storage, minimize exposure to room light, and avoid expo sure to direct sunlight and ultraviolet light. 
 
Do not refreeze thawed vials. 
 
Frozen Vials Prior to Use 
 
Cartons of COMIRNATY multiple dose vials with purple caps and labels with purple borders arrive in thermal 
containers with dry ice. Once received, remove the vial cartons  immediately from the thermal container and 
FDA-CBER-2022-5812-0235972
 
26 preferably store in an ultra-low temperature freezer between -9 0ºC 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 sto rage 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 therm al 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 fo r instructions regarding the use of the thermal 
container for temporary storage. The thermal container maintain s 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 v ials 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 b e 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.  
 
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 expo sure to direct sunlight and ultraviolet light. 
Any vaccine remaining in vials must be discarded after 6 hours.  Do not refreeze.
