There are several possible reasons: (1) Influenza viruses continue to mutate. The World Health Organization monitors and infers the epidemic strains in the new year every year. In some years, the predicted epidemic strains may not exactly match the actual epidemic strains, so There is still a possibility of infection. (2) After vaccination, it takes about two weeks for the body to produce antibodies. Before antibodies are produced, there is still the possibility of infection. (3) It may be infected with other respiratory diseases, causing corresponding flu-like symptoms, so patients will mistakenly believe that the vaccine does not provide immune protection.

wants. In all flu seasons, there are multiple influenza virus strains circulating. Once infected with one virus strain, it will not develop immunity to other virus strains.
