Public Service Announcement:
We now know why some flu vaccinations have not been working at all, against the important H3N2 Flu virus. **
By using eggs, the H3N2 subtype mutates a key viral protein to bind to egg-bird cells.
This egg-specific mutation disrupts the critical region on the flu virus protein that is normally targeted by our immune system.
This means egg-based flu vaccines containing the mutated protein DOES NOT TRIGGER an effective immune response. … This leaves our body without protection against the circulating strains of H3N2 flu viruses.
Solution: ASK your flu virus vaccine provider if their vaccine is egg-based.
Sadly, most US-created flu vaccines are egg-based => likely not worth getting
Instead, choose the less-common non-egg based flu vaccines, like Flublok.
Flublok is a recombinant protein-based vaccine for influenza immunization in adults over age 17 …
