(Gray News) – A nurse in the San Diego-area emergency room tested positive for the coronavirus more than a week after receiving his first dose of Pfizer vaccine.
A nurse named KGTV Matthew W. started feeling sick on Christmas Eve six days after his vaccination and tested positive the day after Christmas.
He works in two hospitals in the San Diego area and was working in the COVID department of a hospital when he started to feel ill.
Experts said this is not unexpected, given that it takes time for immunity to develop – 10 to 14 days – and it is possible to become infected before that immunity develops.
The first shot provides 50% protection, Dr. Christian Ramers, an infectious disease specialist at Family Health Centers in San Diego, to KGTV. The available vaccines against the coronavirus require two doses.
Currently, the Pfizer and Moderna vaccines are approved for use, with the shots being rolled out to target populations first.
The coronavirus pandemic killed more than 336,000 Americans, and experts warn vacation travel could trigger another spike.
