Vaccines for Children is a federal program which covers the cost of vaccines for more than half of American children. The committee’s reversal on Friday standardizes the updated MMRV vaccine recommendations for all children. ACIP has been recommending a hepatitis B vaccine for all newborn babies since 1991, which resulted in a 99% drop in serious infections between 1990 and 2019. “To date, no country in the world has reverted from universal to selective birth dose recommendations,” he added. Correction: An earlier version of this story mischaracterized ACIP’s 1991 recommendation for the first dose of the hepatitis B vaccine.
