A nurse of California has tested positive for COVID-19 just eight days after getting the Pfizer-BioNTech vaccine.
The 45-year-old nurse named Matthew W. in California's San Diego received the vaccine on December 18.
Six days later, Matthew had chills, muscle pain and fatigue after working a shift in the COVID-19 unit. He first got the chills before coming down with muscle aches and fatigue, Matthew told ABC 10 News. Later on December 26, he went to a hospital to get tested for the virus and tested positive.
The scenario isn't unexpected, Dr Christian Ramers, an infectious disease specialist with Family Health Centers of San Diego, told KGTV.
Patients don't immediately develop COVID-19 protection after being vaccinated.
"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.
Even after those 10 to 14 days, patients still need a second vaccine dose for full protection. "That first dose we think gives you somewhere around 50%, and you need that second dose to get up to 95%," Ramers added.
Besides, since the incubation period for COVID-19 can be as long as 14 days, it's also possible that Matthew was infected prior to receiving the vaccine on December 18.
