According to the Centers for Disease Control (CDC), you should allow two weeks after getting a flu shot to develop protection against the flu. That's because after vaccination, the body has to work for a while to create the protective antibodies to the flu virus. Bear in mind, though, that there's a lot of variation in how fast different people's immune systems work.
The flu vaccine is the best way to protect yourself from the influenza virus. You should get one every year, unless you have a medical reason not to. Flu season can begin as early as October and last as late as May. Itâs best to get the vaccine as soon as it becomes available each fall. But you can still get vaccinated in January or later. The flu shot becomes effective about 2 weeks after you get it. Can the Vaccine Give Me the Flu? No. The viruses in the flu shot are dead. Even the nasal spray, which has a weak version of the flu virus, cannot give you the flu. What Are the Possible Side Effects? Most people have no problems from the vaccine. If you get the flu shot, you might have a mild fever and feel tired or achy afterward. Some people also have soreness, redness, or swelling where they got their shot. These problems arenât serious and donât last long.
