All Maryland residents over 16 will be eligible for a COVID-19 vaccine starting on April 27, Gov. Larry Hogan announced Tuesday.

The state has issued more than 2 million vaccine doses as of Tuesday — more than 35% of people in the state over 18, according to the governor.

Following a two-week lull between shipments, additional vaccines from the federal government are on their way and a weekly shipment schedule will resume, he said. Hogan could not provide exact numbers on how many doses the state expects but said he hopes to outpace the Biden administration’s tentative schedule to make all Americans eligible.

“The president’s goal was to open up eligibility by May, and he said finish by the Fourth of July,” Hogan said. “We’d like to be ahead of that time frame…as long as we get the supply.”

Maryland entered phase 2A of its state-wide vaccination program Tuesday, meaning residents 60 and older can be inoculated.

Starting March 30, the state will enter Phase 2B, which allows anyone over 16 with a qualifying medical condition or disability to get a vaccine. People in this priority group began pre-registering on the state’s vaccination site today, and so far, Hogan says more than 150,000 people have signed up.

Starting April 13, Maryland will enter Phase 2C for people over 55 and all essential workers. The state will widen eligibility to anyone over 18 two weeks later.

Several counties, including Prince George’s and Montgomery, have lagged behind the state’s vaccination schedule in the past. George Lettis, spokesperson for Prince George’s County, said the county has moved into Phase 2A and plans to follow the state’s lead so long as vaccine shipments stay on schedule in the coming weeks.

Hogan also announced that Maryland will open six new mass vaccination sites in Timonium Fairgrounds, Hagerstown, and Germantown, as well as Ann Arundel, Fredrick, Howard, and Hartford counties in April, for a total of 12 mass vaccination sites across the state. Officials are also planning to open more in the coming weeks.

So far, more than 400,000 Marylanders have been infected with COVID-19, and more than 8,000 have died from the disease. Hogan said mobile vaccination clinics have made progress distributing the vaccine to hard-to-reach zip codes.

David Marcozzi, COVID-19 incident commander for the University of Maryland, cautioned residents about proliferating variants of the virus, particularly strain B117, which he said has is more contagious and making residents sicker. Marcozzi advised residents experiencing nausea, vomiting, and diarrhea to get tested, as these could be symptoms of the coronavirus variant.

“We are in a race between the variants and vaccination rates,” Hogan added.

Marcozzi stressed that individual interest is crucial to a successful vaccination campaign, and, following reports earlier this week, reminded on-the-fence residents there’s a Krispy Kreme donut in it for them if they get vaccinated.
