Yes. CDC continues to recommend that everyone ages 5 years and older get vaccinated for COVID-19. The known risks of COVID-19 illness and its related, possibly severe complications, such as long-term health problems, hospitalization, and even death, far outweigh the potential risks of having a rare adverse reaction to vaccination, including the possible risk of myocarditis or pericarditis.
If you have already gotten the first dose of Pfizer-BioNTech or Moderna vaccine, or if your child has already gotten the first dose of the Pfizer-BioNTech vaccine, it’s important to get the second dose unless a vaccination provider or your doctor tells you not to get it.
If you have concerns about COVID-19 vaccination, talk with your healthcare provider or your child’s doctor, nurse, or clinic.
