At one point or another, you're going to get the flu. Most likely, you've already experienced the bed-ridden days of bad daytime television and a congested respiratory system peppered with the inability to keep solid food in your body. A flu shot can help you bypass these miserable symptoms. Flu vaccination should not cause the flu in the people to whom it is administered; there are no active viruses in the shot. Some people experience a few mild side effects, but the flu itself is worse than these, making vaccination a good idea for most people.
It takes 14 days for a flu vaccine to become fully active. A small percentage of people who get the vaccine develop a low-grade fever of 101 degrees or less. It is possible that your immune system is aggressively responding to the vaccine.
