No. This is perhaps the most pervasive myth about the flu shot, and it endures for a reason: many people report feeling unwell after receiving the vaccine.
Because the flu shot is made from dead viruses, it cannot (repeat, cannot) give you the flu. However, it can trigger an immune response from your body—which may cause you to experience mild, flu-like symptoms.
It’s important to note: while irritation around the injection site is common, only 1 to 2 percent of people who get the flu shot will have fever as a side effect.
