The side effects of the COVID-19 vaccines are dangerous.
COVID vaccines can have side effects, but the vast majority are very short term, and not serious or dangerous. The vaccine developers report that some people experience pain where they were injected, body aches, headaches, or fever, lasting for a day or two. These are signs that the vaccine is working to stimulate your immune system. If symptoms persist beyond two days, you should call your doctor. If you have a pre-existing condition, or if you have severe allergies — especially ones that require you to carry an EpiPen — discuss the COVID vaccine with your doctor, who can assess your risk and provide more information about if and how you can get vaccinated safely.
