It is one of two in California that are part of a White House program to establish 100 federally-run vaccination sites nationwide in the first 100 days of President Joe Biden's administration.
Workers at Tokyo Medical Center were among the first of some 40,000 medical professionals targeted to receive the initial shipments of the vaccine. Many people have a vague unease about vaccines, partly because their side effects have often been played up by media here.

He also acknowledged he had "no idea" how much of the population will be vaccinated by this summer's postponed Olympics.

Supplies of imported vaccines are a major concern because of supply shortages and restrictions in Europe, where many are manufactured. So far, the government has provided conditional approval to just Pfizer-BioNtech for its vaccine.
Athletes in some countries have already been vaccinated, while other NOCs have said they will wait for other priority groups before seeking vaccines for their competitors.

Organisers and officials have outlined virus countermeasures they say will keep the Games safe even without requiring participants to be vaccinated or quarantined on arrival.
