BAKERSFIELD, Calif. — The first load of coronavirus vaccines has arrived at Los Angeles International Airport, according to a LAX Twitter post Sunday night.

Thousands of vaccines were shipped out of a Pfizer facility in Kalamazoo, Michigan throughout the weekend, with expectations to reach more than 100 destinations across the United States.

"This is a major milestone for science, our country and our community," the LAX tweet said. "Thank you to all those who made this delivery possible, and are part of the incredible effort to distribute vaccines around the world."

The vaccine will be administered to healthcare workers first, according to the state's vaccination plan.

Patients at long term care facilities will be next in line.

According to Governor Gavin Newsom, the state expects about 327,000 vaccines for the first round of distribution.
