More California counties are opening up vaccines to younger adults, a week ahead of the state broadening eligibility to everyone 16 and older.
Still, California public health officials warned on Thursday of decreases in supply because of a national reduction of the one-shot Johnson & Johnson vaccine in coming weeks.
Santa Clara, Alameda, Contra Costa and Fresno counties are the latest to open up vaccinations to everyone 16 and older ahead of the state.
Alameda County has now opened vaccine eligibility for county residents ages 16 and older, although the state's My Turn tool shows that people who work (not live) in Alameda County are eligible, too. Santa Clara, however, has only opened the ability to schedule an appointment now for April 15 or later.
Contra Costa County was the first Bay Area county to widen vaccine eligibility to residents 16 and older. Previously, residents could only make 16+ appointments through the county itself, but those people can now book appointments at locations including Oakland Coliseum through My Turn, or by calling the state's vaccine hotline at (833) 422-4255.
People age 16 and older can get the Pfizer vaccine, while the Moderna and Johnson & Johnson vaccines are for those 18 and older.
On Friday, Facebook announced that it would convert part of its Menlo Park headquarters into a vaccination site and hoped to vaccinate as many as 10,000 people in coming weeks.
Vaccine supplies could shrink when eligibility expands next week.
