The influenza viruses evolve much faster than other viruses we vaccinate against. A vaccination essentially teaches our immune system to identify a disease-causing agent so that it can fight and stop it before it does any harm. Many vaccines contain only parts of the disease-causing agent, which cannot initiate the disease on their own.

Everyone 6 months and older should get a flu vaccine every season with rare exceptions. Vaccination is particularly important for people who are at high risk of serious complications from influenza.

That’s why the timing of the flu vaccine is important. Horovitz pointed out that while the virus mutates, that’s not the only reason you need an annual vaccination. “There are mutations of the...

The influenza viruses in the seasonal flu vaccine are selected each year based on surveillance data indicating which viruses are circulating and forecasts about which viruses are the most likely to circulate during the coming season.

Why is it possible to only be vaccinated once for measles but the flu vaccine is required yearly?

Oh, well for all intents are purposes, there is only one strain of the measles. One vaccinted you are vaccinated forever. (Depending on the vaccine, tetatnus is every 10 years.) But, there are thousands of strains of the flu. Once vaccinated you do stay vaccinated, but each year there are many, many brand-new flus. If you catch the flu you are immune to that strain forever too, which is why the old ones don't keep coming back. The flu vaccine is made to protect against the 3 or 4 that doctors predict will be the worse each season. It doesn't protect against them all and it can't protect against the new mutations that we will see next year. Hope this clears things up for you!
