U.S. nurse tested positive after receiving Pfizer COVID-19 vaccine
U.S. nurse tested positive after receiving Pfizer COVID-19 vaccine. According to the US “Capitol Hill” report, a nurse in California tested positive for the new coronavirus one week after receiving Pfizer’s COVID-19 vaccine. Doctors believe that he may have been infected with the new coronavirus before the vaccine.
It is reported that the nurse received the first dose of the COVID-19 vaccine on December 18, local time, and felt only mild arm soreness. About six days after the vaccination, the 45-year-old nurse began to experience chills, muscle pain and fatigue. The nurse was still working in the new coronavirus pneumonia department of the hospital when she felt unwell. It was not until she tested positive for the new coronavirus that she learned that the previous uncomfortable symptoms were symptoms of new coronavirus pneumonia.
Christian Lammers, an infectious disease expert at the San Diego Family Health Center, told the ABC that it is not surprising to contract new coronavirus pneumonia after vaccination. He explained that it takes a while for the vaccine to have a protective effect on COVID-19. It is known from the experiment that it takes about 10 to 14 days to start to produce protection.”
He added that the first dose of the vaccine itself does not provide complete protection against the virus. We believe that the protective effect of the first dose of the COVID-19 vaccine can reach about 50%, and the second dose can reach 95%.
The nurse may have been infected with the COVID-19 virus before the vaccination on December 28. Since the incubation period of the COVID-19 virus is nearly 14 days, he may not have symptoms until after the vaccination.
