FDA Warns Health Officials Not To Mess With COVID-19 Vaccine Doses Schedule : Coronavirus Updates : NPR

The U.S. Food and Drug Administration is warning health care workers that any changes to the authorized dosing schedules of COVID-19 vaccines currently being administered significantly place public health at risk and undermine “the historic vaccination effort to protect the population” from the coronavirus pandemic. The first and second doses of the Pfizer-BioNTech vaccine are approved to be delivered within a 21-day window, while the Moderna injections should be spread over 28 days. When given at those intervals, both vaccines are about 95% effective, according to the respective drugmakers.
