SACRAMENTO, Calif. (AP) — California will begin sending 40% of all vaccine doses to the most vulnerable neighborhoods in the state to try to inoculate people most at risk from the coronavirus and get the state’s economy open more quickly, Gov. Gavin Newsom said Thursday in the latest shake-up to the state's rules. The doses will be spread among 400 ZIP codes where there are about 8 million people eligible for shots, said Dr. Mark Ghaly, the state's health and human services secretary. Many of the neighborhoods are in Los Angeles County and the central valley, which have had among the highest rates of infection.
