All Massachusetts residents aged 16 and older will be eligible to receive Covid-19 vaccinations starting April 19, according to a new state timeline released Wednesday morning.

The detailed timeline also makes residents aged 60 and older and people in public-facing jobs eligible for the vaccine starting Monday. Residents 55 and older, and people with one co-morbidity, will become eligible on April 5. Currently, only people aged 65 and older, those with two or more co-morbidities and certain classes of workers are eligible to receive the vaccine in Massachusetts.

The schedule was announced in a news release from Gov. Charlie Baker and follows the tiers of priority for vaccinations that was outlined in December. Details, including definitions of co-morbidities and eligible worker groups, are available at

Martha’s Vineyard Hospital head of operations Claire Seguin hailed the news.

“We are encouraged to by the governor’s announcement this morning about reaching this stage of the vaccine rollout,” she said in an email to the Gazette.

“At MVH, we have been preparing for this next phase. We have added staffing, a tented annex for increased capacity, and we have a well-tested process. It is our understanding and hope that the supply will catch up with the demand in the days and weeks ahead.  Once that happens, we will ramp up quickly and accordingly.”

According to Ms. Seguin, as of March 12, the hospital had completely vaccinated (administered both doses) 1,383 people over the age of 65, while 3,349 people over the age of 65 had received a first dose.

“Although it is hard to know the exact number of residents over 65, the Dukes County 2019 census report projects 4,773 by 2020,” she wrote.

The hospital runs age statistics every Friday and starting this week will post them on its website, Ms. Seguin also said.

The hospital is currently scheduling appointments for eligible people through its website on Mondays and Saturdays.

Ms. Seguin said that schedule will stay the same.

New cases of the virus on the Island have slowed dramatically in recent weeks, with an average of just one new positive test per day over the past two weeks. The Island boards of health announced that they would stop providing daily case updates starting next week and would instead provide figures on a weekly basis.

As of Tuesday, a total of 943 people have tested positive for the coronavirus on Martha’s Vineyard since the pandemic began a year ago, and the Island boards of health have documented 57 other probable cases based on symptoms, for a total of 1,000 cases. There have been no confirmed deaths associated with the virus on the Island.
