Cicada: A new Omicron BA.3.2 variant tests vaccines and spread
A newly identified Omicron subvariant BA.3.2, nicknamed 'cicada', carries many mutations that may help it evade immunity. It has appeared in Europe and in 25 U.S. states, but remains a minority strain with no clear evidence of greater severity or transmissibility. Vaccines are still expected to protect against severe illness, annual booster shots are recommended, and home COVID tests remain effective if not expired.
