Pfizer asks for FDA authorization for vaccine for kids under 5
The FDA's advisory committee will meet on Feb. 15 to review the Pfizer vaccine for use in children under the age of 5. The advisory committee is an independent group whose vote is nonbinding, but the FDA takes it into consideration when making a final decision.
The vaccine would still need to go through several other approvals before it can be used on children under the age of 5. It would need to be authorized by the FDA, then the CDC advisory committee would need to meet for recommendations and it would need to be approved by the CDC.
Pfizer and BioNTech said Tuesday they have initiated rolling submission for emergency use authorization for kids 6 months through 4 years old -- at the request of the FDA. Pfizer and BioNTech said they're submitted data for two doses but expect the vaccine to be a three-dose series, and that the data for the third dose will be provided in the coming months.
