Three new U.S. studies offer more evidence that the COVID-19 vaccines are standing up to the omicron variant, at least among people who have gotten booster shots
NEW YORK -- Three studies released Friday offered more evidence that COVID-19 vaccines are standing up to the omicron variant, at least among people who received booster shots.
They are the first large U.S. studies to look at vaccine protection against omicron, health officials said.
The papers echo previous research — including studies in Germany, South Africa and the U.K. — indicating available vaccines are less effective against omicron than earlier versions of the coronavirus, but also that boosters significantly improve protection.
The first study looked at hospitalizations and emergency room and urgent care center visits in 10 states, from August to this month.
