COVID-19 Booster Vaccine Information

Rapid Testing and Booster Update

Early indications are that the protection against the Omicron variant of COVID-19 more than doubles with a booster dose (compared to the primary series of the vaccine).

The Centers for Disease Control recently updated its recommendation for COVID-19 vaccines with a preference for people to receive a Pfizer-BioNTech and Moderna shot over Johnson & Johnson’s vaccine.

In advance of holiday gatherings, the Rhode Island Department of Health (RIDOH) offers the following information about expanded access to rapid testing, COVID-19 booster doses and primary series vaccines:

Rapid and PCR testing sites: visit to make an appointment whether symptomatic or asymptomatic, and for a list of updated locations and details.

Vaccines: Everyone who is 16 and older is eligible to get a booster dose in RI if it has been 6 months from the last dose of the two dose Pfizer or Moderna vaccines or 2 months from the initial Johnson & Johnson vaccine. Primary series COVID-19 vaccine is available for persons 5 years of age and older. To make an appointment and get additional information, visit or call 844-930-1779.

Boosters for those who are not immunocompromised, who received the Moderna or Pfizer vaccine at least six months after their second dose of the Moderna or Pfizer vaccine:

Only certain populations initially vaccinated with the Moderna or Pfizer-BioNTech vaccine should get a booster shot at this time:

  • People aged 65 years and older and adults 50-64 years with underlying medical conditions should get a booster shot
  • Residents aged 18 years and older of long-term care settings should get a booster shot of.
  • People aged 18-49 years with underlying medical conditions may get a booster shot based on their individual benefits and risks.
  • People aged 18-64 years at increased risk for COVID-19 exposure and transmission because of occupational or institutional setting may get a booster shot based on their individual benefits and risks.
  • Occupations at increased risk for COVID-19 exposure and transmission include front line essential workers and health care workers as previously detailed by the CDC (which may be updated in the future) as follows:
  • First responders (healthcare workers, firefighters, police, congregate care staff)

Boosters for those who are immunocompromised:

Moderately to severely immunocompromised persons who have already received two doses of the Pfizer or Moderna vaccine more than 28 days ago are eligible and no doctor’s order or note is required. Immunocompromised people are/have:

Booster and immunocompromise third  doses are available at many retail pharmacy, medical, state-run and hospital sites as well as community vaccination clinics throughout Rhode Island. Visit or call 844-930-1779 or 2-1-1. Be sure to pay attention to the specific vaccine being administered at the site if this matters to you.

Rhode Island uses a self-attestation model for people who are moderately to severely immunocompromised or have other qualifying conditions or work duties. They will not be required to provide documentation of their health status or work duties.
