The United States military has begun rolling out its first COVID-19 vaccinations in Japan, prioritizing front-line medical workers.

Inoculations began Monday at the Yokota Air Base, Lt. Stuart Thrift confirmed.

Last week, U.S. Forces Japan took delivery of just under 8,000 doses, a military spokesman said during a FaceBook Live event Tuesday.
