Wisconsin health officials say that only 0.03% of people who have been fully vaccinated for the coronavirus have tested positive for COVID-19. The number of so-called breakthrough cases was just 605 out of 1.8 million people who are fully vaccinated. Fond du Lac County Public Health Officer Kim Mueller says there are breakthrough cases being reported locally. Mueller says Fond du Lac County is seeing on average about one breakthrough case a day, and about half of those cases involving individuals without any symptoms. Mueller says much like the flu vaccine, people who do become sick after receiving a COVID-19 vaccine tend to have milder symptoms. The state’s number of breakthrough cases is higher than the national rate of 0.008% reported by the U.S. Centers for Disease Control and Prevention. The CDC has said that the national tally is an undercount and some infections are expected among those who are immunized because no vaccine is 100% effective.
