Dec 15. White House chief medical advisor Dr. Anthony Fauci said Wednesday that currently available booster shots work against the omicron variant of Covid-19 and do not need to be adjusted to fight the new, highly contagious strain of the virus at this time.
“Our booster vaccine regimens work against omicron,” Fauci told the public during a White House Covid update on Wednesday. “At this point, there is no need for a variant-specific booster.”
Fauci said the primary two-dose vaccination series from Pfizer and BioNTech is significantly compromised by omicron, but still offers considerable protection against severe disease. Protection from the two-dose vaccine against infection dropped to 33% compared with 80% before the emergence of omicron. However, two doses are still 70% effective at preventing hospitalization in omicron patients in South Africa, Fauci said.
