COVID in California 

California is seeing a spike in COVID-19 cases, most of them the highly transmissible Delta variant that has proliferated since the state fully reopened its economy on June 15. 

The vast majority of new cases are among unvaccinated people. 

Seven Bay Area counties are recommending residents wear masks indoors, while Los Angeles County officials reinstated the indoor mask mandate regardless of one’s vaccination status. 

Additionally, the University of California system said all students, faculty, and staff must be vaccinated against the coronavirus in order to return to campuses.

UC President Michael V. Drake said in a letter to the system’s 10 chancellors that unvaccinated students without approved exemptions will be barred from in-person classes, events, and campus facilities, including housing. 

California will require everyone in schools to wear masks despite new guidelines issued by the CDC that says fully vaccinated teachers and students can drop face masks. 

Hospitalizations in California are at the highest level since April, but they are a far cry from the winter peak, officials said. 

Other counties, including Sacramento and Yolo, are strongly urging people to wear masks indoors.

Vaccines decrease the severity of the illness, reduce hospitalizations and decrease the risk of death. Clinical trials showed that a single dose of the J&J vaccine was 72% effective against moderate to severe COVID-19 in the United States, compared with 95% for the Pfizer and Moderna vaccines. 

A Food and Drug Administration analysis cautioned that it’s not clear how well the vaccines work against each variant.

So-called breakthrough cases among the vaccinated are unusual. Between Jan. 1 and June 30, California identified 8,699 such cases out of the more than 20 million who have received the vaccine. 

State health officials continue to urge everyone to get vaccinated, but they would not say if statewide restrictions are coming. A spokesperson said, in part, 

“We continue as always to support the ability of local health jurisdictions to enact stricter local public health guidance that is tailored to the situation in their communities, as some counties have done.”

The Inside California Politics/Emerson College poll was conducted July 19-20, 2021. The sample consisted of California registered voters, n=1,085, with a Credibility Interval (CI) similar to a poll’s margin of error (MOE) of +/- 2.9 percentage points.
