Flu Shot Side Effects
Many people worry about side effects from the flu shot, but serious complications are rare. Some people believe that they can actually get the flu from receiving the shot, but this is not the case. For the majority of people, the risks of developing the flu are far greater than any risks associated with the vaccine.
Most side effects and reactions to the flu shot are mild. Most commonly, people experience a soreness, redness, or mild swelling at the site where the shot was given. These effects generally do not last for more than 2 days. In rare cases, people may develop other mild reactions to the flu vaccine like fever and aches, which may mistakenly lead them to believe that they developed the flu as a result of the vaccine. These symptoms also go away after about 1 to 2 days. Because the flu shot contains inactivated, or killed, virus particles, there is no possibility of contracting the infection from the flu shot.
- Allergic reactions to the flu shot are very rare.
