Santa Clara County will require health care workers in high-risk settings to get COVID-19 boosters, and to get them sooner than a statewide mandate issued by Gov. Gavin Newsom last week, officials announced Tuesday.
Last week, Newsom announced that nearly all of California’s roughly 2.5 million frontline health care workers must receive a COVID-19 booster shot by Feb. 1. Santa Clara County’s order goes into effect on Jan. 24, and will apply to more workers than the state’s.
At the Tuesday press conference, Santa Clara County Public Health Officer Sara Cody said a surge in omicron variant infections drove the decision to order the mandate.
“Since the last time we spoke, which was just less than two weeks ago, I warned of a deluge of omicron,” Cody said. “Today, unfortunately, that deluge is here.”
COVID-19 cases among the unvaccinated are higher now in Santa Clara County than last August’s surge. While 81% of county residents are vaccinated, and 52% have gotten a booster dose, Cody said the high spread of omicron meant a possibility for hospitals here to become overwhelmed soon — making even the “breakthrough” cases in vaccinated people a problem for hospitals.
“Even if a small portion ends up needing a hospital bed, it could still end up being a lot of people, because the portion of cases is quite large,” Cody said.
The order, she added, is “to protect our health care system.”
Both the state’s and the county’s orders apply to workers at hospitals and doctor’s offices, home health workers and those working in high-risk congregate settings including nursing facilities, hospice centers and dialysis centers.
But Santa Clara County’s order “applies to a slightly broader set of workers,” said County Counsel for Santa Clara County James Williams, “namely medical first responders, such as paramedics and EMTs, those working in shelters, and non-health care staff in jails and correctional settings.” It also will not allow unvaccinated or unboosted people to get tested as a way to satisfy the requirement.
Instead, those workers without a booster, including medical and correctional first responders, will be reassigned to jobs within their organizations that the county doesn’t consider having high-risk settings, such as where air is shared with high-risk clients, and jails, said Williams.
“Boosters are absolutely critical, given what we’re facing right now,” he said.
