Vaccines are here to help protect against serious illness from COVID-19. Due to limited  supply the Health Department will be prioritizing vaccinating our most vulnerable residents, Phase 1B: Adults ages 75 and older. It may take a couple of weeks before we are able to register other eligible populations in Phases 1B & 1C.

Maryland will distribute the vaccines to five different priority groups based on relative risk of exposure or developing serious illness.

Vaccine prioritization may be subject to change. The state has adopted a rolling vaccine allocation model, meaning it may not wait for every member of a particular group to get vaccinated before moving ahead; individuals will still have the opportunity to be vaccinated in subsequent phases.

Registration Process

To assist you in the online vaccine registration process, the Health Department has created an eligibility prescreening form to gather contact information that will be used to communicate vaccination clinic registration information.
