US Officials Extend Expiration Dates On Vaccines...



Johnson & Johnson said Thursday that U.S. regulators extended the expiration date on millions of doses of its COVID-19 vaccine by an extra six weeks.

The company said a Food and Drug Administration review concluded the shots remain safe and effective up to 4 and a half months. The shots were originally approved for just 3 months.

The announcement comes after state officials warned that many unused doses in storage would expire before the end of the month.

Expiration dates for vaccines are determined based on data the manufacturer submits to regulators proving how long the shots stay at the right strength.
