SANTA ANA, Calif. (AP) — California is expanding vaccine eligibility to anyone 50 and over starting in April and anyone 16 and over on April 15.

Gov. Gavin Newsom said Thursday that the state expects to receive 2.5 million doses a week in the first half of April and more than 3 million a week in the second half of the month.

That’s a big jump from the roughly 1.8 million doses a week the state is currently getting.

“With vaccine supply increasing and by expanding eligibility to more Californians, the light at the end of the tunnel continues to get brighter,” said Gov. Newsom. “We remain focused on equity as we extend vaccine eligibility to those older than 50 starting April 1, and those older than 16 starting April 15. This is possible thanks to the leadership of the Biden-Harris Administration and the countless public health officials across the state who have stepped up to get shots into arms.”

 The state has the capacity to administer more than 3 million vaccines per week, and is building the capacity to administer 4 million vaccines weekly by the end of April.

The move comes as some California counties have veered away from the state’s vaccine eligibility criteria by opening up the shots for people with a broader range of medical conditions and at younger ages than the 65 and over required in most counties.
