California is vaccinating children ages 16 and over and many counties have started offering the vaccine.  You can search sites by zip code at VaccineFinder.org and sign up for Ca Sites at MyTurn.Ca.gov

UCSF Benioff Childrens Hospital starts vaccinating ages 16-21 years on April 15th and is making appointments for Oakland and SF Sites by phone call only (they are currently NOT using myturn):

For either location, please call (415) 514-1196, Monday to Saturday from 7 a.m. to 7 p.m. and Sunday from 8 a.m. to 5 p.m. Choose option 2, and stay on the line to speak with an operator, who will schedule an appointment. Be sure to identify which location you want.
