A nurse in California tested positive for COVID-19 more than a week after receiving Pfizer Inc's vaccine, an ABC News affiliate reported on Tuesday. Six days later on Christmas Eve, he became sick after working a shift in the Covid-19 unit, the report added. He went to a drive-up hospital testing site and tested positive for COVID-19 the day after Christmas, the report said. Christian Ramers, an infectious disease specialist with Family Health Centers of San Diego, told the ABC News affiliate that this scenario was not unexpected. "We know from the vaccine clinical trials that it's going to take about 10 to 14 days for you to start to develop protection from the vaccine," Ramers said.
