“Before we start talking about a fourth shot, it would be very important for us to determine the durability of protection,” Dr. Anthony Fauci said Wednesday.
— though more research is needed about how well the current boosters prevent severe disease.
“Before we start talking about a fourth shot, it would be very important for us to determine the durability of protection, particularly against severe disease for the third-shot booster of an mRNA [vaccine] and the second shot of a [Johnson & Johnson],” Fauci said at a White House COVID-19 task force press briefing.
Fauci warned that Omicron has been better at evading the immunity provided by vaccines, causing breakthrough infections.But he said that “boosters bring back up that degree of protection to a level that is approximately what it was before.”Currently, the seven-day average for new cases nationwide is 240,400 per day, up around 60% from the previous week, the Centers for Disease Control and Prevention said.
