Discussion Summary:  
x The ADD for the supplement, June 17, 2022, was discussed in the context of 
submissions related to COVID-19 vaccines in the near future. Due to the increased OVRR workload anticipated for June, the ADD may be difficult to meet. Therefore, the review team will complete as much as possible in the next month with a check-in to occur in early to mid-May to determine if the action on the sBLA can be taken before the end of May or if it will need to be deprioritized to take action after June 17th.  
x The clinical reviewer presented the key findings from the supplement and also 
highlighted the differences between the data that were submitted to support the EUA versus the sBLA. 
 Report and Discuss:   1. Reviewer Reports   
a. Clinical (Susan Wollersheim) 
x The review is ongoing and no substantive issues have been identified. 
x The remaining items to be reviewed/completed are: 
i. Subgroup analyses for immunogenicity and safety 
ii. Narrative details of SAEs 
iii. PeRC paperwork 
x PMR/PMC studies are not needed. x Target date the review will be completed: May 2, 2022. Moving the 
deadline upwards will depend on supervisory input and their workload. 
 
b. Biostatistics (Ye Yang) 
x The review is ongoing, and no substantive issues have been identified. x Target date the review will be completed: May 31, 2022 x The majority of the review is completed.  The date of completion is 
flexible, and it can be moved up if needed. 
FDA-CBER-2022-5812-0500357
 4 x There have been minor updates to the solicited reactions and 
immunobinding data, and these updates  will need to be included in the PI. 
 
c. Benefit-Risk Assessment (Hong Yang, Osman Yogurtcu and Patrick Funk) 
x The real-world effectiveness data for this age group are similar to those for 
the older pediatric age group 16-18 years of age. The vaccine efficacy 
information included in the submission is also similar between these age groups. 
x We do not expect new data for myocarditis in this age group from FDA 
BEST due to limited sample size. However, available VAERS data and 
data from Israel indicated a relatively lower myocarditis risk for this age group compared to the group 16-18 years of age. 
x A recently conducted seroprevalence study by the CDC demonstrated that 
about 57% of the unvaccinated population tested positive for SARS-CoV-2 
antibodies, indicating a great extent of exposure to the SARS-CoV-2 among the unvaccinated population. The reviewers questioned how much protection prior exposure could provide, and how this could potentially lower the benefit of the vaccine. 
x Management summarized several studies which demonstrate an added 
benefit of vaccination for individuals with prior infection; therefore, there is agreement that there are still added benefit from the vaccination for the people with prior infection. Management will share the referenced studies/presentations with the reviewers. [Post-meeting note: Management shared the CDC slides and other literature with the reviewers.] 
x The reviewers will review the information and vaccine benefit. Additional 
quantitative benefit-risk analysis may not be needed for this age group. 
x Target date the review will be completed: May 18, 2022 (can be flexible if 
needed). 
 
d. Real World Evidence (Yun Lu) 
x Target date the review will be completed: May 18, 2022 (can be flexible if 
needed). 
x Real World Evidence (RWE) studies show high effectiveness in this age 
group. However, the studies that were submitted were conducted during the pre-Delta or Delta predominant period, and there is no RWE associated with this age group during the Omicron predominant period. 
x The reviewer does not consider this a major concern since there are 
publications outside of this submission which can be reviewed. She will look for new publications with Omicron data and will update the team. 
 
e. Epidemiology/Pharmacovigilance (Deborah Thompson) 
x Date the review will be completed: Review is complete. 
x No substantive issues were identified, and the draft review memo is under 
supervisory review.  
FDA-CBER-2022-5812-0500358
 5 x The PMRs and PMCs are the same as those identified in the August 23, 
2021, Comirnaty Approval Letter. During the authorization of emergency 
use for younger age groups, including adolescents 12-15 years of age, we requested that relevant age groups be included in post-authorization studies. PMRs #7, #8 and #9 are specifically focused on younger age groups and include individuals 12-15 years of age. The respective protocols have already been revised, if needed, to include this age group with the exception of PMC #10 Pregnancy Registry Study (C4591022). An IR will be sent asking the sponsor to revise the Pregnanc y Registry Study 
protocol and SAP to include pregnant individuals of all ages. 
x No safety issues have been identified that would warrant new PMRs or 
PMCs. The clinical reviewer concurred with this decision. 
 
f. BIMO (Kanaeko Ravenell and Char-Dell Edwards) 
x Target date the review will be completed: 30 days after receipt of the 
completed Establishment Inspection Report (EIR) package. 
x All BIMO inspections have been completed and no FDA form 483s were 
issued. The review will be completed within two weeks of receiving the 
EIRs if the reviewer concurs with ORA’s recommendations. 
 
g. CMC (Xiao Wang) 
x Target date the review will be completed: April 15, 2022. 
x There are no updates at this time, and no substantive issues have been 
identified. 
 
h. APLB (Oluchi Elekwachi) 
x Target date the review will be completed: May 10, 2022. x Comments will be discussed during the upcoming labeling meetings. 
 
i. CDISC (Brenda Baldwin) 
x Target date the review will be completed: by the end of April 2022. x There are no new comments at this time. 
 
2. If the application will be discussed at an Advisory Committee (AC), review potential 
issues for presentation.  
No. At the January 31, 2022 Filing meeting, DVRPA management confirmed that this application does not need to go to VRBPAC. 
 3. Determine whether Postmarketing Requirements (PMRs), Postmarketing 
Commitments (PMCs), or a Risk Evaluation Mitigation Strategy (REMS) are needed.   No safety issues have been identified that would warrant new PMRs or PMCs beyond those that were included in the August 23, 2021 Approval Letter for the original Comirnaty BLA (STN 125742/0).
