Vaccinated people may be more likely to develop a breakthrough coronavirus infection with the Omicron variant than with Delta, but vaccines still keep most people out of the hospital, US Centers for Disease Control and Prevention Director Dr. Rochelle Walensky said Wednesday.
“What I can tell you is that compared to people who are boosted, if you are unvaccinated, you are 10 times more likely to be a case and 20 times more likely to be a fatality. Compared to people who are (vaccinated), you are 17 times more likely to be in the hospital,” Walensky said at a White House Covid-19 briefing.
“So our vaccines are working really well to prevent severe disease and hospitalization and death. They're actually also working quite well to prevent cases, although we do know more breakthrough cases are happening in the context of Omicron,” she added.
And it’s too soon to consider asking people who are boosted to get another dose, said Dr. Anthony Fauci.
“Before we start talking about a fourth shot, it will be very important for us to determine the durability of protection, particularly against severe disease for the third shot booster of an mRNA and the second shot of a J&J. Right now, we don't have that information,” Fauci, who is director of the National Institute of Allergy and Infectious Diseases, said at the briefing.
“It is conceivable that in the future, we might need an additional shot, but right now, we are hoping that we will get a greater degree of durability of protection from that booster shot,” Fauci added. “So we're going to take one step at a time, get the data from the third boost and then make decisions based on the scientific data.”
