The past two weeks have been full of exciting COVID-19 vaccine news, including the FDA’s emergency use authorizations (EUAs) for the Pfizer–BioNTech and Moderna vaccines and the nationwide rollout of Pfizer’s vaccine. Choosing how to allocate access to vaccine doses has been left to individual states, leaving policymakers with difficult decisions about how to prioritize their populations, complicated in part by the federal government’s reduction in some vaccine shipments.
With a limited supply of doses, who should get the first shots? Some commentators have suggested prioritizing children early for a host of reasons, including hope about children returning to school. Last month a New York Times column asserted that “saving the most lives could mean prioritizing the vaccination of children and young adults.” But there is an important reason that kids can’t be part of the vaccine line yet: we don’t know whether these vaccines work for them. In this post, we explain why COVID-19 vaccines are only just starting to be tested in children and what policymakers can do to spur pediatric vaccine trials.
