Although a flu shot can decrease your chances of getting the flu, viruses change all the time, so preventing the flu can be tricky. The vaccine is the best prevention method, but recently approved medicines (such as Tamiflu) can help with prevention if you take them for at least two weeks during an outbreak.
Flu Prevention: An Overview
Flu prevention is hard because flu viruses change all the time. This year's flu virus is usually slightly different from last year's virus. Every year, the flu shot is updated to include the most current flu virus strains, which is one reason why flu shots will only protect you for one year.
