SAN FRANCISCO — A hospital in Northern California quickly vaccinated 850 people after a freezer that was holding doses of the Moderna coronavirus vaccine failed, prompting officials to do an emergency distribution before the shots spoiled.

The Adventist Health Ukiah Valley Medical Center in Mendocino County told the Ukiah Daily Journal that it sent 200 doses to the country that were dispensed to county workers, including sheriff’s deputies and jail staff. Jail inmates also received shots.

Eighty doses were sent to nursing homes.

Hospital spokeswoman Cici Winiger says the rest were distributed at four makeshift clinics on a first-come, first-serve basis after the hospital sent out a social media blast alerting people that vaccinations were available.
