Maine is leading almost every state in distributing the coronavirus vaccine. The Bangor Daily News is tracking how many vaccines have been administered and other aspects of Maine’s rollout here.

Data on Maine’s vaccinations comes from the Maine Center for Disease Control and Prevention and the governor’s office, while data for other states is from the U.S. Centers for Disease Control and Prevention. The chart showing how many Mainers have been vaccinated is updated daily, while other charts are updated weekly or biweekly.

How many Mainers have been vaccinated?

More than 800,000 Mainers have received at least one dose of the coronavirus vaccine after it was approved in mid-December. Both the Pfizer and Moderna vaccines must be administered in two doses several weeks apart, while the Johnson & Johnson vaccine is given in one dose.

Supply is no longer a constraint in Maine’s vaccine rollout, while health officials are continuing to  work to find ways to reach people who have yet to be vaccinated. All people aged 12 and older are eligible to receive a vaccine at this point.

How does Maine compare to other states?

There is wide variation among states in terms of the share of populations vaccinated, with New England states leading the pack, according to federal data. Southern states, including Mississippi, Alabama and Arkansas, trail with less than half of their populations having received at least one dose.

Maine ranks relatively well compared to other states in terms of the speed of its vaccine distribution. Most of the states that have been the most efficient in their vaccine distribution are rural states with smaller populations.

Where are the most Mainers vaccinated?

Vaccination rates vary widely by county and even zip code, with some municipalities seeing more than 90 percent of their residents vaccinated while others have yet to see even a third of their populations get at least one dose. 

Generally, southern and coastal towns in Maine have seen the greatest shares of their populations vaccinated, while inland and northern parts of the state have lagged. Percentages calculated by the state are based on 2018 population estimates, so they may not be exact.
