A week after receiving Pfizer vaccine Nurse tests positive for COVID-19

A nurse in the United States has tested positive for COVID-19 eight days after having received a Pfizer vaccine shot. 45-year-old Matthew W., who works as an ER nurse at two hospitals in San Diego, received the jab on December 18.

Speaking to ABC news affiliate, he said that - after receiving the vaccine, his arm sore for a day but he suffered no other side effects.

However, six days later on Christmas eve, the 45-year-old became sick while working a shift in the COVID-19 unit. He got the chills and later came down with muscle aches and fatigue, ABC reported. The next day, he tested positive for COVID-19.

As per the report, Matthew's condition has improved since his symptoms peaked on Christmas Day but still feels fatigued.

Dr Christian Ramers, an infectious disease specialist with Family Health Centers of San Diego, said that such cases were not unexpected because ur was "exactly what we would expect to happen if someone was exposed."

Ramers who serves on the clinical advisory panel for the United States vaccine roll out, said, "it is possible that Mathew was infected before receiving the vaccine, as the incubation period may be as much as two weeks. Additionally, we know from the vaccine clinical; trials that it is going to take about 10 to 14 days to develop protection from the vaccine."

"That first dose we think gives you somewhere around 50%, and you need that second dose to get up to 95%," Ramers added.

He further said that he knew of several other local cases where health care workers became infected around the time they received the vaccine.
