It was the 10th time in the last 11 days that new cases have been below 100, but progress could be impeded if more young and rural residents don’t get vaccinated.

Vaccinations, meanwhile, have slowed down dramatically as the state looks for new ways to entice those who have held out.

It’s not clear yet how long vaccines will protect against infection, but studies are underway to answer that question.

The state reported 71 new cases as it crossed the 60% threshold for eligible residents, age 12 and older, who have been fully vaccinated.
