The vaccine to cure every strain of flu

Current flu vaccines focus on two proteins on the surface of the virus. However, these constantly mutate in a bid to fool the immune system, making it impossible for vaccine manufacturers to keep up with the creation of each new strain.

The universal vaccines focus on a different protein called M2, which has barely changed during the last 100 years.

The protein is found in all types of Influenza A, including the current bird flu and the virus that caused the 1918 Spanish flu pandemic which killed up to 50 million across the globe.
