December 30, local time, according to the Hill, a nurse in California tested positive for the novel coronavirus a week after receiving the Pfizer coronavirus vaccine.
It is reported that the nurse received the first dose of the coronavirus vaccine on December 18 local time, when she only felt a slight sore arm. About six days after vaccination, the nurse began to feel chills, muscle pain and fatigue.
The nurse still worked in the hospital’s COVID-19 department when she felt uncomfortable. It was not until she tested positive for COVID-19 that she learned that the previous symptoms of discomfort were symptoms of COVID-19.
Christian Ramos, an infectious disease specialist working at San Diego’s home health center, responded by saying it’s not surprising to get COVID-19 after vaccination because it takes 10 to 14 days for a vaccine to protect people from COVID-19.
Ramers added that the first dose of the vaccine is only 50% likely to protect people from the novel coronavirus, and only 95% after two doses of the vaccine can be reached.
And the nurse may have contracted the novel coronavirus before vaccination, but due to the incubation period of the virus for nearly 14 days, all his symptoms did not begin to appear until after vaccination.
