Bivalent COVID-19 vaccines, which contain both the original strain of the virus and the Omicron variant, protected kids and teens from infections and COVID-19 symptoms better than the first, single-strain vaccines during a period when Omicron BA.4/5 variants were circulating, according to a US study. The study of almost 3000 kids found that the bivalent vaccines have an effectiveness of 54% against infection and 49% against symptomatic COVID-19. The authors say their data demonstrates the benefits of COVID-19 vaccines in children and adolescents.
