(CMR) With an ER nurse testing positive for COVID-19 eight days after receiving the Pfizer vaccine, people who receive the vaccine may need to continue observing other COVID-19 protocols such as wearing a mask and social distancing.
According to ABC News, Matthew W, a 45-year-old nurse in San Diego, received the Pfizer vaccine on December 18 and only experienced arm soreness.
Six days later, after working a shift in the COVID-19 unit, he had chills, muscle pain, and fatigue.
Two days later, a drive-up hospital test confirmed he was positive for COVID-19.
However, disease experts say this is not unexpected since the vaccine should provide protection 10 to 14 days after it is first received.
According to disease experts, the Pfizer vaccine's first dose is expected to offer 50 % protection, with the second dose offering at least 95% protection from the coronavirus.
However, there is also the possibility that the nurse had the virus before taking the vaccine since the incubation period can be as long as 14 days.
Over two million Americans have been vaccinated since the Pfizer and Moderna vaccines rollout across the country.
