Chief White House medical adviser Anthony Fauci said Wednesday he thinks it will be known later this year if and how often COVID-19 vaccination boosters should be administered.


During a House Appropriations Committee hearing on the proposed budget for the National Institutes of Health (NIH), Rep. John Moolenaar (R-Mich.) asked Fauci what he thought the future of coronavirus vaccination looked like.


“Well it’s very clear right now if you look at the need for vaccination — I mean if you look at the hospitalizations and deaths of those who are unvaccinated compared to those who are vaccinated and boosted, the data are stunning. They’re striking, the difference,” Fauci said.

He added that it was “very clear” that a booster is necessary in the “era of omicron,” pointing to the strength of the protection that a third shot offered. However, he acknowledged that protection has been seen to wane over time and said it was currently unclear if annual boosters would be needed due to the new variants that continue to arise.


“I think some time in the middle of the summer we’re gonna know what the cadence is gonna be about how often we’re gonna have to vaccinate people,” said Fauci.
