How COVID-19 Affects Children

While children have been less affected by COVID-19 compared with adults, children can get sick from COVID-19 and can spread COVID-19 to others. Children with underlying medical conditions are at increased risk for severe illness.

Facts About the COVID-19 Vaccines for Children

  • CDC recommends that everyone 6 months and older get a COVID-19 vaccine [external link] to help protect against COVID-19. Children 6 months and older are now able to get either the Pfizer-BioNTech or the Moderna COVID-19 vaccine. 
  • Side effects observed in clinical trials were similar to those observed for COVID-19 vaccines for adults and similar to other routine pediatric vaccines. Most side effects are mild and go away on their own within a few days.
    • Common side effects may be:
      • Tiredness
      • Headache
      • Muscle pain
      • Chills
      • Fever
      • Nausea
      • Redness, pain and swelling on arm of injection.
  • COVID-19 vaccines and other vaccines, such as influenza or other routine childhood vaccines, can be administered together.

How to Get a COVID-19 Vaccine for Your Child
