On December 30th, local time, according to the US Capitol Hill, a nurse in California tested positive for the new crown virus a week after receiving Pfizer's new crown vaccine.
It is reported that the nurse received the first dose of the new crown vaccine on December 18, local time, and felt only mild arm soreness.
About six days after the vaccination, the nurse began to feel chills, muscle pain and fatigue.
The nurse was still working in the new coronary pneumonia department of the hospital when she felt unwell. It was not until a positive test for the new coronavirus that she learned that the previous uncomfortable symptoms were symptoms of new coronary pneumonia.
Christian Lammers, an infectious disease expert working at the Family Health Center in San Diego, responded to this, saying that it is not surprising to contract new crown pneumonia after vaccination, because the vaccine takes 10 to 14 days to protect people from being infected by the new crown virus. .
Ramos added that the first dose of the vaccine is only 50% likely to protect people from being infected by the new coronavirus, and 95% can be reached after two doses of the vaccine.
The nurse may have been infected with the new coronavirus before the vaccination, but because the incubation period of the virus was nearly 14 days, all his symptoms did not begin to appear until after the vaccination.
