(Gray News) – A nurse in the San Diego area of San Diego tested positive for the coronavirus for more than a week after receiving his first dose of Pfizer vaccine.
A nurse calling KWTV Matthew W. became ill on Christmas Eve, six days after his vaccination, and tested positive the day after Christmas.
He was working at two hospitals in the San Diego area and working in the COVID unit of a hospital when he started feeling sick.
Experts said this is not unexpected, as it takes time to develop immunity – 10 to 14 days – and it is possible to become infected before the immunity develops.
The first shot offers 50% protection, said dr. Christian Ramers, a specialist in infectious diseases at Family Health Centers of San Diego, told KGTV. The vaccines available against the coronavirus require two doses.
Currently, the Pfizer and Moderna vaccines have been approved for use, with the shots being rolled first to the targeted population.
The coronavirus pandemic has killed more than 336,000 Americans, and experts warn that holiday travel could cause another rise.
