WHO Panel OKs AstraZeneca Vaccine Against COVID-19 Variants VOA News A World Health Organization panel of immunization experts Wednesday recommended the use of the AstraZeneca COVID-19 vaccine for all ages and in regions where variant strains of the virus are prevalent. The WHO Strategic Advisory Group of Experts (SAGE) on immunization made the recommendation from agency headquarters in Geneva. The panel reviewed the vaccine this week after South Africa halted its use Sunday in response to a study by a university there that indicated the drug provided only minimal protection from the variant that was first discovered in that country. .
