Is it true that the flu vaccine only protects you from last years strain? should i get the vaccine even if i have never had the flu before?

Please do get the: Flu shot. No, the flu shot doesn't just protect against last year's strain. Careful monitoring is done to determine the composition of the new year's flu shot.

Chasing the strains: The flu mutates often and at least 5-6 strains circle the globe at any one time.The flu vaccine is made up of 3-4 strains that cause the highest percentage of flu in the world during the jan-march period, representing the latest mutations.They are placed into closely monitored production and testing so a safe vaccine can be available in aug-sept. New strains will come along, but this protects most.
