White House urges COVID boosters to protect against spreading BA.5 subvariant

BA.5 is estimated to account for 65% of the coronavirus variants circulating in the United States as of last week, said Rochelle Walensky, the director of the U.S. Centers for Disease Control and Prevention (CDC). Officials urged people who are 50 years old or older to get a booster shot and said that would not prevent them from getting another 'bivalent' booster designed to fend off Omicron more specifically later this year.
