U.S. health officials are recommending COVID-19 booster shots for all Americans to boost their defenses amid the delta variant surge.
After struggling for months to persuade Americans to get the COVID-19 vaccine, U.S. health officials could soon face a fresh challenge: talking vaccinated people into getting booster shots to gain longer-lasting protection as the delta variant sends infections soaring again.
As early as Wednesday, U.S. health authorities are expected to recommend an extra dose of the vaccine for all Americans eight months after they get their second shot, according to two people who spoke to The Associated Press on condition of anonymity to discuss internal deliberations.
That means the biggest vaccination drive in U.S. history is about to get even more extensive.
The move is being driven by both the highly contagious variant and preliminary evidence that the vaccine's protective effect starts dropping within months.
