How the Flu Shot Works The flu shot contains live strains of the types of flu viruses that researchers determine are likely to be most prevalent this year. The most common cause of the flu are types of Flu Strain A, but most shots also have two types of Flu Strain B within them in order to protect against these as well. While it is a common misconception, the flu shot cannot give you the flu. That’s because the strains of the virus in the shot are inactivated, not live. While mild, flu-like symptoms are sometimes reported after the vaccine, these are a result of your body creating antibodies to be able to fight the virus if you are exposed. It takes about two weeks for your body to be fully prepared to fight the flu.
Benefits of the Flu Shot
While no one likes receiving a shot, the benefits of the flu vaccine far outweigh the brief discomfort it can cause. Some of the benefits include:- You are less likely to get sick yourself.
- You are less likely to transmit the disease to others, especially those with compromised immune systems.
- You are helping those who cannot get vaccinated, such as babies under 6 months of age.
- You are lowering your risk of complications as a result of the flu infection.
- If you do get sick, the severity of your symptoms will likely be greatly reduced.
