On December 16th, the CDC updated recommendations for individuals to receive a Pfizer or Moderna mRNA COVID-19 vaccine if available over Johnson & Johnson’s COVID-19 vaccine. This recommendation is based on the latest evidence on vaccine effectiveness, vaccine safety and rare adverse events, and consideration of the U.S. vaccine supply.

Given the current state of the pandemic both here and around the world, receiving any vaccine is better than being unvaccinated. Individuals who are unable or unwilling to receive an mRNA vaccine will continue to have access to Johnson & Johnson’s COVID-19 vaccine.

Potential Side-Effects

After the vaccination you may have some side effects, which are normal signs that your body is building protection. These side effects may affect your ability to do daily activities, but usually go away in a few days.
