(Reuters) – A nurse in California tested positive for COVID-19 more than a week after receiving the vaccine from Pfizer Inc, an ABC News affiliate bit.ly/2L8iBel reported on Tuesday, but a medical expert and the American pharmacist said that the body takes more time to create protection.
Pfizer “will review all available information on this case and all reports of any confirmed diagnoses after vaccination,” the drug maker said in a statement to Reuters.
“According to our Phase 3 safety and efficacy study, the vaccine provides some protection against COVID-19 within 10 days of the first dose and is substantially potentiated after the second dose, supporting the need for a series of vaccination. of 2 doses, “he said. .
“People may have contracted the disease before or immediately after vaccination,” the statement added.
Matthew W., 45, a nurse at two different local hospitals, said in a Facebook post on Dec. 18 that he had received the Pfizer vaccine and told the ABC News affiliate that his arm hurt for a day, but that she had suffered no further side effects.
Six days later, on Christmas Eve, he fell ill after working a shift at the COVID-19 unit, the report added. It gave him chills and later he had muscle aches and fatigue.
He went to a testing site at a hospital and tested positive for COVID-19 the day after Christmas, according to the report.
Christian Ramers, an infectious disease specialist at San Diego Family Health Centers, told the ABC News affiliate that this scenario was not unexpected.
“We know from clinical trials of the vaccine that it will take 10 to 14 days to start developing the protection of the vaccine,” Ramers said. “We think that first dose gives you about 50%, and you need that second dose to get to 95%.” –SOURCE reuters.com/article/us-health-coronavirus-usa-vaccine.
