On March 9, 2021 The Centers for Disease Control and Prevention (CDC) Director Dr. Rochelle Walensky said those vaccinated against Covid-19 are unlikely to carry the virus, eliminating the risk that they would be contagious to others. [1]

We’re vaccinating so very fast, our data from the CDC today suggests that vaccinated people do not carry the virus, don’t get sick — and it’s not just in the clinical trials, but it’s also in real world data,” said Walensky to MSNBC’s Rachel Maddow

According to Walensky, 93 million Americans have received at least one vaccine dose, and 51 million have received both doses, yet cases/infections are increasing and around 1,000 people per day are dying with COVID-19

In less than a month, on April 1, 2021 the CDC “walks back” Walensky’s controversial claim, stating “the evidence isn’t clear” and that she was “speaking broadly”! [2]  The CDC spokesperson told the NY Times ““It’s possible that some people who are fully vaccinated could get Covid-19. The evidence isn’t clear whether they can spread the virus to others. We are continuing to evaluate the evidence.””
