U.S. is tracking several omicron subvariants, but new boosters should offer protection, White House says.
Dr. Ashish Jha, head of the White House Covid task force, said health officials are keeping a close eye on several coronavirus omicron subvariants because they render many treatments ineffective.
But the new booster shots should provide a much higher degree of protection against them because they are all descendent from omicron BA.2 or omicron BA.5, Jha told reporters at the White House.
People should get their new booster by Halloween so they have protection by the time families gather for Thanksgiving, he said.
