As with any vaccine, people can react differently. It’s important to know that even rare, severe side effects will be temporary and should not dissuade vaccine recipients from completing their course of injections.

Many people who receive vaccines will have no side effects. Some will have mild side effects, which may include:

  • Low-grade fever
  • Chills
  • Soreness at the injection site
  • Headache
  • Slight fatigue

In rare cases, people may experience more serious side effects, which are defined as side effects that prevent daily activities. These uncommon, temporary but severe side effects may include:

  • Immediate allergic reaction
  • High fever
  • Muscle pain
  • Joint pain
  • Nausea

Anyone who reacts to a COVID-19 vaccine should have either an allergy consultation or referral to consider a second dose. Even if you have side effects, it is still important to get a second dose.

There is no chance the vaccine will cause COVID-19.
