COVID-19 vaccines authorized for use have gone through clinical trials involving tens of thousands of participants to determine their safety and efficacy. The known and potential benefits of the vaccine far outweigh the known and potential harms. To take extra precautions, after you receive the COVID-19 vaccine, you will be required to stay an additional 15 minutes for observation to monitor any potential side effects. Like many vaccines, a COVID-19 vaccine may cause some minor temporary discomfort. Some of these include a sore arm, tiredness, headache, muscle pains, chills, joint pain, fever, injection site swelling, redness, nausea, feeling unwell, and swollen lymph nodes. There is a small chance that vaccines will cause a severe allergic reaction, which is why you are required to stay for observation. It should also be noted that the COVID-19 vaccine will NOT give you COVID-19. None of the COVID-19 vaccines currently in development use the live virus that causes COVID-19.
