A universal flu vaccine would be a flu vaccine effective against all human -adapted strains of influenza A and influenza B regardless of the virus sub type, or any antigenic drift or antigenic shift.[1][2][3][page needed] Hence it should not require modification from year to year in order to keep up with changes in the influenza virus. As of 2024 no universal flu vaccine had been successfully developed, however several candidate vaccines were in development, with some undergoing early stage clinical trial.[4][5]
