The vaccine may be used on adults and children aged3 three years and above.   H1N1 and H3N2 of Influenza A, and Victoria and Yamagata lineages of Influenza B are the common strains of human flu viruses. Until now, China had only three-strain vaccines4 on the market.   The seasonal5 flu is an acute respiratory infection caused by influenza viruses, affecting seniors, infants, and people with cardiopulmonary diseases in particular.
