More than 400 people are hospitalized with COVID-19 in Maine for the first time, state officials reported Monday.

The state’s grim new record of 403 people hospitalized with the virus comes as the omicron variant spreads and infections climb. Just under three weeks ago, Maine’s peak hospitalizations from the pandemic stood at 387. 

Of those currently hospitalized, 107 people are in critical care and 57 are on ventilators, leaving 53 critical care beds available statewide, including eight for children. 

The state Center for Disease Control and Prevention has recorded an additional 1,203 COVID-19 cases since Friday and four more deaths, with a full update from the weekend due out Tuesday. 

One person recently reported to have died was from Androscoggin County, one from Kennebec County, one from Penobscot County and one from York County. Two were in their 50s, one in their 70s and one over 80. Three were male and one was female. 

Also Friday, the state updated its periodic report on the number of vaccine breakthrough cases for the first time since mid-December. There have been just over 26,000 breakthrough cases, representing 22.3% of cases reported since Mainers could be fully vaccinated. 

Five hundred and thirty-two breakthrough cases have resulted in hospitalization and 248 have led to death. That’s 24.7% of hospitalizations in the same period, and 28.3% of deaths. 

The state CDC’s COVID-19 data page says this is likely an undercount of the true number of breakthrough cases, and adds that studies show the COVID-19 vaccine is still essential to prevent serious illness, though like all vaccines, it’s not 100% effective. 

“Even though some vaccinated people may still get sick, data from these studies also showed that COVID-19 vaccines were very effective at preventing hospitalization and death from COVID-19,” the state CDC site says. “That means if you do get sick after you're fully vaccinated, you still have a much lower chance of developing severe disease.”
