Quick Hits: Today’s Top Stories

• The Food and Drug Administration (FDA) on Wednesday formally amended the emergency use authorizations for the Johnson & Johnson and Moderna COVID-19 vaccines so that any recipient of the Johnson & Johnson vaccine age 18 and older may receive a booster dose at least two months after their initial shot, and recipients of the Moderna vaccine older than 64 (or “occupationally exposed” to the virus/otherwise at high risk for severe illness) can get a third dose six months after their second. The FDA also announced Americans can—pursuant to the aforementioned restrictions—“mix and match” their original and booster regimens, using whichever vaccine they prefer for the latter. The Centers for Disease Control (CDC) will likely issue its own recommendations in the coming days.

• With the FDA and CDC set to meet in the coming weeks to discuss authorizing COVID-19 vaccinations for children ages 5 to 11, the Biden administration announced plans on Wednesday to “ensure that, if a vaccine is authorized for children ages 5-11, it is quickly distributed and made conveniently and equitably available to families across the country.”

• The Washington Post reported yesterday that internal U.S. Customs and Border Protection data show American immigration officials detained 1.7 million people along the southern border in the 2021 fiscal year, the highest annual figure on record.
