I've heard that the flu vaccine can cause the flu. What's the truth?

The truth is that there are many different vaccines, and some of them can cause mild side effects such as soreness or swelling at the injection site. But these symptoms are very rare, and they usually go away quickly. In fact, the CDC recommends that you get vaccinated to help protect yourself from serious illnesses like influenza. So it’s important to talk to your doctor about which vaccines are best for you.
