(Gray News) – An emergency nurse in the San Diego area tested positive for coronavirus more than a week after receiving her first dose of the Pfizer vaccine.
A nurse who KGTV calls Matthew W. began to feel unwell on Christmas night, six days after his inoculation, and tested positive the day after Christmas.
He was working at two hospitals in the San Diego area and was working in a hospital’s COVID unit when he began to feel sick.
Experts said this is not unexpected, as it takes time for immunity to develop (10 to 14 days) and it is possible to become infected before immunity develops.
The first shot provides 50% protection, Dr. Christian Ramers, an infectious disease specialist at San Diego Family Health Centers, told KGTV. Available coronavirus vaccines require two doses.
Currently, the Pfizer and Moderna vaccines have been approved for use, with the first shots at specific populations.
The coronavirus pandemic has killed more than 336,000 Americans and experts warn that holiday travel could cause another rise.
