New confirmed cases of Covid-19 dropped to their lowest level in four months last week, the Island boards of health reported Monday in a regular update.

Four people tested positive for the coronavirus — two in their 30s and two in their 40s — for the week ending Saturday, Nov. 6. Three of the four were fully vaccinated and the fourth was unvaccinated, according to the boards of health report, which also report that two of the people were symptomatic and the other two showed no symptoms.

It was the lowest number of new cases on the Island since early July. After declining to just eight cases in the month of June, case counts began to climb, reaching a high of 97 in a single week in late August, then dropping again.

According to the Martha’s Vineyard Hospital, nearly 15,000 people have been fully vaccinated on the Island against Covid-19, and more than 1,300 booster shots have been administered. Currently, only people who are 65 and older, live or work in a high-risk setting or are immune-compromised are eligible to receive a booster shot.

Last week, the hospital began scheduling vaccine appointments for children ages 5 through 11, following emergency approval of pediatric use of Pfizer vaccine by the Food & Drug Administration. Vaccine clinics will be held starting Thursday.
