A scientific surprise: vaccinated and unvaccinated COVID-19 patients may carry similar amounts of virus

Noted: The study started in Dane County and contains a disproportionate level of samples from that area, cautioned David O’Connor, one of the authors of the new study and a professor of pathology and laboratory medicine at the University of Wisconsin-Madison.

Scientists stressed that despite having comparable levels of virus, vaccinated patients remain far less likely than the unvaccinated to become severely ill, hospitalized or die from COVID-19.

Also, O’Connor said the 83 Dane County cases showed that unvaccinated people are more than twice as likely to get the virus as those who’ve been vaccinated.

“What we’re seeing here is that the vaccines are doing a superb job of keeping people out of the hospital,” O’Connor said.
