Medical professionals can best advise individuals on whether or not they should receive a COVID-19 vaccine. However, based on available evidence, people with the following health conditions should generally be excluded from COVID-19 vaccination in order to avoid possible adverse effects:

• If you have a history of severe allergic reactions to any ingredients of the COVID-19 vaccine

• If you are currently sick or experiencing symptoms of COVID-19, though you can get vaccinated once your primary symptoms have resolved.

Further research is needed to determine the safety and efficacy of different COVID-19 vaccines in certain population groups. In addition to the general recommendations above, each vaccine may have specific considerations for specific populations and health conditions.
