The Centers for Disease Control and Prevention has endorsed updated COIVD-19 boosters. The decision opens the way for a fall vaccination campaign that could blunt a winter surge if enough Americans roll up their sleeves. The new boosters targeting today’s most common omicron strains should begin arriving in pharmacies and clinics within days. The decision by CDC Director Rochelle Walensky came shortly after the agency’s advisers voted in favor of the recommendation. The shots made by Pfizer and rival Moderna offer the most up-to-date protection at yet another critical period in the pandemic.
