The reasons why some are positive even after the vaccine COVID-19

Stephen Lynch from Massachusetts did the same. He proved positive after taking the second dose of Pfizer vaccine. Hall of Fame basketball coach Rick Pitino, who leads the men's team in Iona College in New York, also came up positive after taking his first dose, Knn reports.

They could have resulted positive for several reasons:

There is a delay between vaculation and protection: It takes a few days until a few weeks for vaccines to work, according to the U.S. Centers. A. about Disease Control and Prevention. You can get positive before the vaccine begins.

Vaccination prevents most, but not all diseases: You can still get positive after you're vaccinated because the vaccine is not 100% effective. Both US authorized vaccines. They are very effective, but they do not offer total protection.

Vaccination prevents disease, but it's still unclear whether, or how many, vaccines prevent all infections: “The information is less clear if vaccines will prevent the virus from infecting us, and we can remain free of symptoms. This is still under study”, Dr. William Schaffner, an infectious disease specialist and a professor of preventive medicine at the Department of Health Policy at Vanderbilt University.

Vaccines don't function retroactively: You could get positive because you were infected before you took the vaccine and you just didn't know it yet.

Option question: There is concern that certain options have spread to the U.S. may be less sensitive to the protection resulting from vaccines. The lab's preliminary data shows that vaccines must provide protection, and public health managers want to vaccinate as many people as soon as possible to limit the virus's ability to screw up.
