COVID-19 Vaccine Boosters for Employees in High-Risk Settings

COVID-19 vaccines continue to be highly effective at preventing severe illness, hospitalization, and death due to COVID-19, including from the Delta variant. But protection appears to decrease over time, and some people are at increased risk of getting and spreading COVID-19 because of where they work. As a result, some people are now eligible for a booster shot.

Who Is Eligible for a Booster

You’re eligible to get a booster shot if:

  • It's been at least 6 months since you got the second dose of a Pfizer-BioTech or Moderna vaccine;
  • You're at least 18 years old; and 

  • You work in certain high-risk settings.

Examples include:

  • First responder (such as firefighter or police officer)
  • Health care worker
  • Education staff (such as teacher, support staff, or daycare worker)
  • Food and agriculture worker
  • Factory worker
  • Corrections worker
  • U.S. Postal Service worker
  • Public transportation worker
  • Grocery store worker

If your workplace is not listed above, your health care provider can help you decide if a booster is right for you.

CDC recommends that all individuals who are at least 18 years old and who got Johnson & Johnson’s Janssen vaccine—regardless of whether you work in a high-risk setting—get a booster at least 2 months after your first dose.

If you're eligible for a booster, you may choose which vaccine to receive as a booster dose. Your booster shot doesn't have to be the same vaccine you received before. 

For more information about boosters, or if you have questions about your eligibility, visit or talk to a health care provider.
