Pfizer’s COVID Vaccine on Hold for Infants/Toddlers

The FDA has just announced that they plan to postpone their scheduled advisory committee meeting on Pfizer’s COVID-19 vaccine for children ages 6 months to 4 years. They do not expect to reconvene for a few more months pending additional data required to move forward.  

A two-dose vaccine series failed to meet “immunobridging” criteria in a study evaluating the youngest children. Pfizer explained in a previous statement that a third dose “may provide a higher level of protection in this age group.” The ongoing clinical study plans to evaluate a third dose at least two months after the second dose of the two-dose series in this age group of children.

The FDA ultimately decided that “additional time regarding a third dose should be considered,” and postponed the advisory committee meeting until further data was available.
