You got a coronavirus vaccine but still became infected. How did that happen?

Within the past week, positive coronavirus test results were delivered to at least three New York Yankees players, an Olympic gymnast alternate, multiple state lawmakers from Texas, a White House official and a staffer in House Speaker Nancy Pelosi's office. They also had this in common: All were fully immunized with coronavirus vaccines, their cases known as breakthrough infections.

The rash of such cases might suggest the coronavirus is regularly blasting by vaccinated people's immune barriers. But these breakthrough infections are not surprising, nor do they suggest vaccines are widely failing.

"Breakthrough infections are to be expected, even when you have highly effective vaccines," said Roy Gulick, chief of infectious disease at Weill Cornell Medicine in New York. To understand why is to understand what vaccines are, and are not, capable of.
