The Maine Center for Disease Control and Prevention on Saturday reported 289 new cases of COVID-19 and one additional death after the state’s adult population passed the 50 percent milestone for full vaccination this past week. Meanwhile, the number of coronavirus hospitalizations in Maine edged up to 134 on Saturday from 127 the day before.

Mainers 16 and older are now fully vaccinated against COVID-19 at a rate of 51.15 percent, according to Maine CDC statistics. MaineHealth has opened vaccine registration to teenagers as well, anticipating federal approval of the Pfizer vaccine for ages 12 to 15. Young people, meanwhile, are still driving new cases. Of Saturday’s 289 new cases, 135 were in people under 30, or about 47 percent.

Maine’s cumulative COVID-19 cases rose to 63,750 on Saturday. Of those, 47,202 have been confirmed by testing and 16,548 are considered probable cases of COVID-19. The seven-day average of new daily cases was 304.9.

Seven hundred ninety-five people have died with COVID-19 in Maine since the pandemic began. The person reported Saturday to have died was a Franklin County man aged 80 or older, the Maine CDC said.

Maine still has among the highest vaccination rates in the country, with its full vaccination rate 10 percentage points above the national average. Only Connecticut, New Hampshire, Massachusetts and Vermont were ahead of Maine in the percentage of population having received a first dose of a COVID-19 vaccine.

“I am proud to report that more than half of Maine people have received their final dose of a vaccine – but there is more work to do to get this pandemic behind us,” Gov. Janet Mills said in a statement Friday. “We will continue our efforts to expand access to the vaccine, to get into hard-to-reach communities and to deliver shots into arms. I encourage everyone to get vaccinated so that we can defeat this virus and its variants and get back to normal as soon as possible.”

Pfizer, meanwhile, is seeking full approval for its COVID-19 vaccine, and schools such as the University of Maine are closely watching. The vaccine currently has an emergency use authorization from the Food and Drug Administration, and some schools have been reluctant to require vaccination until the shots are fully approved.

If the Pfizer vaccine does receive full approval, the University of Maine System is likely to require it for students and staff this fall, Chancellor Dannel Malloy said.

“I think people are entitled to know that it has been fully tested and vetted before we as a state system would require it,” Malloy said.

Bowdoin College and the University of New England, among others, already have made vaccination mandatory.

By Saturday morning, Maine had given 652,242 people the first dose of a COVID-19 vaccine, and 575,539 had received a final dose. Out of the state’s population of 1.3 million, 48.52 percent had received a first dose.

Among people 16 and older, the population currently eligible for vaccination, 51.15 percent are now fully vaccinated.
