Pfizer-BioNTech booster targeting variants as safe as earlier COVID shots, 30-day data shows
USA Today, November 4, 2022
One variant that's now growing exponentially in the U.S., called BQ.1.1, is "very troublesome," according to Pei-Yong Shi, associate chief research officer and vice president for research innovation at the University of Texas Medical Branch at Galveston. "Whether the bivalent vaccine will work against this in terms of protection in the United States — the answer to that is I'm not quite sure," he said. People who have been boosted with the bivalent shot have some neutralizing antibodies against BQ.1.1, research he posted Wednesday shows, "but it's pretty low."
