Omicron offshoot BA.3.2 spreads across 25 states, vaccine protection under review

A newly identified Covid variant, BA.3.2, is spreading in the United States with evidence from travelers and wastewater tests across at least 25 states. Descended from Omicron and carrying many spike-protein mutations, it may evade protection from current vaccines. While not yet dominant or associated with more severe disease, scientists warn that vaccines might need updating and continued surveillance is essential.
