The tetravalent vaccines contain both seasonal influenza A subtypes, A(H3N2) and A(H1N1)pdm09, and both influenza B lineages, B/Victoria and B/Yamagata. It needs to be noted however that as of January 2024, influenza B/Yamagata viruses have not been circulating since March 2020. Trivalent vaccines contain one of the two B lineage virus components.
