Experts here in the bay area say it takes time for antibodies to develop in your body.

Regarding what happened to the nurse in San Diego, “My guess is that they were exposed just before they received the vaccine and had no symptoms yet or soon after,” said Dr. Herold.

“It is a sad coincidence that if someone has already been exposed and vaccinated, the vaccine does not work in a few days. I mean, it works in a few days, but certainly not in less than a week,” said Dr. Yvonne Maldonado, from Stanford .

Doctors told ABC7 News that the first injection of the vaccine gives 50 percent immunity, which does not happen in one week with the Pfizer vaccine and two weeks with the Modern vaccine. The second dose increases immunity to at least 90%.

Although neither is 100 percent, Dr. Herold says there is optimism in her hospital and she couldn’t help but smile when she received the vaccine.

“Under my mask, I have the biggest smile that I’m finally getting,” she says, “because it looks like hope now and for all of us who are taking care of patients with COVID and have kind of reached the limit now. Having something to wait and wait for is a very powerful thing. “
