“[COVID-19] will not take the summer off. It didn’t take spring break off. It didn’t take the easter weekend off. It remains as deadly as it’s ever been,” Newsom said.

Ahead of Thursday’s expansion, numbers released by the state show nearly half of California has already gotten at least one shot of the either the Pfizer, Moderna or Johnson & Johnson COVID-19 vaccine.
