State data shows sharp contrast between vaccinated, unvaccinated


The Wisconsin Department of Health Services (DHS) released data on Thursday comparing cases, hospitalizations and deaths among vaccinated and unvaccinated populations since February, showing a marked disparity between the two populations on all measures.

In July alone, an unvaccinated person was nearly three times more likely to become infected, 3.7 times more likely to be hospitalized and 10 times more likely to die than a person who’d been vaccinated.

The data are expressed as a rate of people per 100,000, rather than a total number of people. Less than two percent of the population was fully vaccinated on February 1, whereas nearly half were by July 1.

The number of cases, hospitalizations and deaths in both groups fell sharply in June only to rebound in July.

“The increase in cases we are seeing in Wisconsin right now is being largely driven by the Delta variant, and the overwhelming majority of people who are contracting COVID have not been fully vaccinated. With the original strain of COVID-19, an infected person was likely to infect two other people, who were then likely to infect two additional people for a total of 6 cases from one infection. With the Delta variant, an infected person is likely to infect about five people, who are then likely to infect 25 people for a total of 30 cases from one infection,” DHS Secretary-designee Karen Timberlake said in a press release. “The COVID-19 vaccines are still doing their job by stopping the spread of many new infections, and by preventing severe illness, hospitalization, and death.”
