The Minnesota Department of Health has identified 89 “breakthrough” cases of COVID-19 in the state. That’s when a person who is fully vaccinated after two weeks still gets infected. Health officials say the number isn’t surprising because the vaccine is not 100-percent effective, and it is mostly used to stop severe symptoms from forming in case of infection. Over half of those cases were asymptomatic. This is why experts like Director of Infectious Diseases Kris Ehresmann say it is still important to follow COVID protocols so vaccinated people don’t pass it along to the unvaccinated.
