MADISON, Wis. (AP) — Nearly 200 Walgreens pharmacies across Wisconsin are expecting to receive coronavirus vaccines directly from the federal government starting this week, marking the beginning of a program that targets underserved areas, state health officials announced Thursday.

The vaccinations will be provided for free under the state and federal partnership, the Wisconsin Department of Health Services said. Initially, there will be about 17,800 doses of vaccine sent to 178 Walgreens locations across the state.

All who are eligible for vaccination, which includes anyone over age 65, must schedule an appointment by phone or through the Walgreens website, the state health department said.

The state cautioned that due to limited supply, not everyone eligible will be able to get a vaccination appointment.

“It’s true that we’re getting more shots in arms, but the vaccine is still a scarce resource, and we have plenty of masks to go around, so mask up,” Gov. Tony Evers said in a statement.

Wisconsin now ranks ninth nationally in the percentage of the population that has received at least one dose of the vaccine, according to the U.S. Centers for Disease Control and Prevention. Wisconsin vaccination rate of 10.6% is ahead of the national average of 10.2%.

Wisconsin has administered at least one dose to nearly one-in-three people over age 65, the state health department said. To date, more than 860,389 vaccinations have been given and 197,362 people are fully vaccinated, the health department said.

In addition to people over age 65, those eligible for the vaccine include front-line health care workers, residents of nursing homes and long-term care facilities, police, firefighters and those who work in prisons.

Positive cases of COVID-19 have been trending downward in Wisconsin since they reached a peak in mid-November. The seven-day average of new cases is at its lowest point in five months. To date, nearly 552,000 people have tested positive and 6,129 have died.
