Universal flu vaccine

The Influenza virus has both hemagglutinin and neuraminidase spikes that are being used as antigen binding sites in the search for a universal vaccine.

A universal flu vaccine is a flu vaccine that is effective against all influenza strains regardless of the virus sub type, antigenic drift or antigenic shift.[1][2][3][page needed] Hence it should not require modification from year to year. As of 2021 no universal flu vaccine had been approved for general use, several were in development,[1] and one was in clinical trial.[4]
