I'm worried about the safety of vaccines. What is the latest research on their safety and effectiveness?

The latest research shows that vaccines are generally safe and effective at preventing diseases. However, there have been rare cases of serious side effects, such as allergic reactions or anaphylaxis, which can occur with any medical procedure. In addition, some people may develop a mild fever, soreness, or swelling at the injection site after receiving a vaccine. These symptoms should go away within a few days. It is important to consult with your doctor if you have concerns about possible side effects from vaccines.
