Has anyone tested positive for COVID-19 after vaccine?

How long does it take to build up immunity to COVID-19 after receiving the vaccine?
COVID-19 vaccines teach our immune systems how to recognize and fight the virus that causes COVID-19. It typically takes a few weeks after vaccination for the body to build protection (immunity) against the virus that causes COVID-19. That means it is possible a person could still get COVID-19 just after vaccination.

Does COVID-19 vaccine increase immunity following an infection?
Tafesse's research has found vaccination led to increased levels of neutralizing antibodies against variant forms of the coronavirus in people who had been previously infected. “You will get better protection by also getting vaccinated as compared to just an infection,” he said.
