"Kaiser and PAMF are responsible for the majority of Santa Clara County residents, the majority of our residents are their patients, but we don't have full visibility into what they're doing," said Williams.

Most residents will receive the vaccine from their primary care provider, but the county has already ramped up capacity to vaccinate up to 6,000 people a day with plans to do more once the vaccine supply becomes more stable.

But Stanford Health Care has stepped up to help providing mutual aid by accepting more than 500 transfers in the past two months alone.
As people anxiously wait their turn for the vaccine, medical providers are once again reminding the public about ways to prevent the spread of COVID-19.
"We know how you can protect yourself. We know that if you maintain social distancing and wear a mask, you will be able to protect yourself from this virus," said Prof. Andra Blomkalns, M.D., Stanford School of Medicine.
