The former head of the Food and Drug Administration said Sunday that he predicts there will be a “backstop” to prevent a new strain of the omicron variant of COVID-19 from becoming a problem.

“A fully boosted person may be more protected against this new variant than they were against the original strain of omicron,” said Scott Gottlieb on CBS’s Face the Nation with host Margaret Brennan. “So far, based on what we’ve seen out of Denmark and the U.K., which are collecting very good data on this, it doesn’t appear to be a more virulent strain.”
