SAN DIEGO, California – In Southern California, a nurse began showing symptoms of COVID-19 six days after receiving the vaccine, and tested positive two days later.

Experts say this happens because antibodies take a long time to develop in the body.
“I have no problem putting people in needles as a doctor, I don’t particularly like them putting needles in me,” said Dr. Amy Herold, chief physician at Queen of the Valley Medical Center in Napa, California.

He took the coronavirus vaccine just like thousands of others.

As for what happened to the nurse in San Diego, “my guess is that they were exposed just before they got the vaccine and they still had no symptoms or just after,” Herold said.

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

Doctors informed our sister channel KGO-TV that the first vaccine gives 50% immunity, which does not start for a week with the Pfizer vaccine and two weeks with the Modern vaccine. Then the second dose provides at least 90% immunity.

Although neither is 100%, Herold said there is optimism in his hospital and he couldn’t help but smile when he received the vaccine.
“Under my mask, I have the biggest smile I finally have because I feel like a hope right now and for all of us who are caring for patients with COVID and we are on the edge,” he said. “Having something to wait for and wait for is a very powerful thing.”
