The Calvert County Health Department has updated guidance on eligibility requirements for residents who wish to register for a booster or third dose of the COVID-19 vaccine. Under new guidance, all citizens ages 16 or older, who have received either the initial Pfizer or Moderna vaccinations, are eligible to receive a booster dose. At least four months must have passed since the second dose of the initial vaccine to be eligible for a booster. Previous guidance only allowed individuals ages 50 or older, and those who are immunocompromised to receive the booster shot.

Citizens who originally received the Johnson & Johnson (J&J) vaccination must have a note from their personal physician or nurse practitioner recommending a booster dose. Limited supply of the J&J vaccine is available. Citizens should talk to a healthcare provider about the possibility of receiving a Pfizer or Moderna booster if the J&J vaccine is unavailable.

Citizens are reminded that the Calvert County Government has reopened an information call center to assist eligible residents who wish to register for a booster or third dose of the COVID-19 vaccine through the Calvert County Health Department. For questions or assistance scheduling an appointment, residents may call 410-535-0218, Monday, Wednesday or Friday between 10 a.m. and 3 p.m.

It is strongly recommended that citizens working in one of the following fields take advantage of the increased protection of a booster dose:

  • Nursing home and assisted living staff
  • Healthcare workers
  • First responders
  • People who work or live in congregate residential facilities
  • Public transit and school bus drivers
  • Teachers/classroom staff and daycare staff
