Wisconsin health officials say 605 people in the state have tested positive for COVID-19 after full vaccination

Nearly 1.9 million people in Wisconsin have received a full vaccine series

LA CROSSE, Wis. (WKBT) – Wisconsin health officials say a fraction of people who have been fully vaccinated for coronavirus have tested positive for COVID-19.

The number of so-called breakthrough cases was just 605 out of 1.8 million people.

While you may have heard of concerns after vaccination, a vaccine expert with Gundersen Health System says there is an explanation for that.

“There is actually a bias we introduce to this whole understanding of the vaccines. Because people that have an understanding of the vaccines because people that have side effects are much more likely to share their story,” said Gundersen Health System’s Dr. Raj Naik.

The CDC says no vaccine is 100 percent effective.
