The influenza viruses mutate or change at a very high rate. They evolve by two ways: drift and shift. Drift means that small changes or mutations happen to the virus gene, while the shift refers to sudden, major changes on the surface proteins of the flu viruses.
The evolution rate is unrivaled – up to 1 million faster than humans. Thus, flu vaccines need to be updated every year to match this creature's uncanny agility. Studies found that by interfering with activities of the host proteins called Chaperones, we can prevent the viruses from being resistant to the existing vaccines.
