I'm a little concerned about the safety of vaccines. What are your thoughts on vaccines?

I think vaccines are generally safe, but there is some risk associated with them. The most common side effects are soreness and swelling at the injection site, fever, and mild to moderate reactions like headaches and fatigue. These side effects are usually mild and go away quickly. In rare cases, more serious reactions can occur, such as an allergic reaction or a neurological problem. However, these risks are extremely small compared to the benefits of vaccination.
