About 13 percent of the people who live in Alaska have already gotten a shot. That’s higher than states such as West Virginia, which has received a lot of attention for a successful vaccine rollout and has inoculated 11 percent of its people.

But the challenge for Alaska has been how to get vaccines to people across difficult, frigid terrain — often in remote slivers of the state?

“Boats, ferries, planes, snowmobiles — Alaskans will find a way to get it there,” said the state’s chief medical officer, Anne Zink, 43.

Alaskans are being vaccinated on fishing boats, inside 10-seater planes and on frozen landing strips. Doctors and nurses are taking white-knuckle trips to towns and villages across the state to ensure residents are protected from the coronavirus.
