Get vaccinated. Don't spread the flu.

Is the Seasonal Flu Vaccine Effective?

Getting the flu vaccine every year is one of your best defenses against fighting flu. For the 2016-17 seasonal influenza season, the flu vaccine will provide protection against four seasonal flu strains. Every year, scientists monitor the global spread of flu and decide which flu strains will likely cause the most illness during flu season. Those strains are then put into the flu vaccine for that year, so each year the vaccine is different. It is important to get the flu vaccine every year because the viruses change from year-to-year and the protection provided by the vaccine decreases over time.

According to the data gathered by Canada’s sentinel surveillance network, a Canadian vaccine effectiveness study showed significant protection of 64% overall and 56% for adults between 20 and 64 years of age against medically-attended laboratory confirmed influenza A (H1N1) infection.  On average, flu vaccines range from 50 to 70% effective against the viruses in circulation in any given year.
