Which has worst side effects the flu or vaccine?

The flu

The flu is a respiratory illness caused by influenza viruses that can cause mild to severe illness. Symptoms of the flu can include fever, cough, sore throat, runny or stuffy nose, muscle aches, headaches, and fatigue. In some cases, the flu can lead to serious complications, such as pneumonia, bronchitis, and hospitalization.

The flu vaccine is a safe and effective way to protect yourself from the flu. The vaccine is made from a weakened or killed influenza virus, so it cannot give you the flu. However, some people may experience mild side effects from the vaccine, such as soreness, redness, or swelling at the injection site, low-grade fever, headache, and muscle aches. These side effects usually go away within a few days.

In comparison, the flu is much more likely to cause severe side effects, such as pneumonia, bronchitis, and hospitalization. Therefore, the flu is considered to have worse side effects than the flu vaccine.

| Side effect | Flu | Flu vaccine |
