collected in the e-diary, as presented in Tables 5 and 6 of the draft package insert.

Thanks again Mike for the query.The team would like to clarify question 2 noted below: FDA Question: Please clarify whether additional  solicited adverse reac tion data for adolescents 
12 through 15 years of age in Study C4591001 have been collected up to the September 2, 2021 
data cutoff since EUA issuance. Please submit updated solicited adverse reaction frequencies as appropriate, annotating any changes to the results.
In Study C4591001, in participants who originally  received placebo, were unblinded (i.e. after 
EUA issuance) and then received BNT162b2 after unblinding, events related to reactogenicity 
were not reported using an e-diary but were instead reported as AEs. We would like clarify if Michael J.
