Walensky was referring to a new CDC study of nearly 4,000 frontline workers, some vaccinated and some not, who tested themselves weekly for COVID-19 infections between December and March.
Among fully vaccinated people in the study, there were only three "breakthrough" COVID-19 infections detected. In stark contrast, unvaccinated participants in the study logged 161 COVID-19 cases.
This is a great sign, because it means that vaccinated people likely protect those around them from catching the coronavirus very, very well.
But, more data is still needed to say so definitively, which is why researchers are currently recruiting thousands of college students across the country to find out more about the likelihood of asymptomatic spread of this virus among vaccinated people.
"We hope that within the next five or so months we'll be able to answer the very important question about whether vaccinated people get infected asymptomatically, and if they do, do they transmit the infection to others," Dr. Anthony Fauci, the nation's top infectious-disease expert, said at a White House COVID-19 task force briefing on Friday.
On MSNBC, Walensky also spoke about the challenges ahead for the country to exit the pandemic.
New, more transmissible virus variants are spreading fast, at a time when a majority of younger US adults have not been vaccinated quite yet. Walensky shared her fears about a forth surge on the horizon this spring.
"We've done so well in vaccinating the more senior members of our society that deaths might not be what we would expect with prior surges. It's also the case, though, that, you know, if we don't see those number of deaths, the deaths that we're going to see is among younger people," Walensky told Maddow. "Obviously, we don't want to see those either."
