A COVID-19 vaccination clinic in Orono today is being offered to the University of Maine community, and to the public, with no appointments necessary.

So far, about half of Maine's eligible population has received at least their first vaccination shot. It's good news, that's helping the state government to make progress in getting things opened back up, like with the elimination of the mask mandate in outdoor locations and the suspension of Maine's travel restrictions.

In an effort to get as many residents vaccinated, as possible, and because of diminishing demand for appointments, some places are offering the shots with no pre-registration required. That's what's going on today at the University of Maine in Orono.

Between 1 and 5 o'clock this afternoon, people can just show up at the Wells Conference Center on the Orono campus, to receive a vaccination shot. They will even have a choice of either the one-shot Johnson & Johnson vaccine, or the two-shot Moderna vaccine. The second Moderna vaccination also will be given at a clinic at Wells Conference Center. I'm sure they will give people information about when that will take place, once they get their shot.

You don't need an appointment for this clinic, and proof of insurance is not required. However, if you do have medical insurance, they encourage you to bring your card, so that any administrative costs can be billed to your provider. There are no out-of-pocket costs for this procedure.

University of Maine students, staff, and faculty are encouraged to take part in this clinic, but it's also open to community members.
