Didn’t you hear that CDC recommended vaccinated wear masks? It’s pretty common knowledge why they did that.
“Our vaccines are working exceptionally well,” Walensky told CNN’s Wolf Blitzer. “They continue to work well for Delta, with regard to severe illness and death – they prevent it. But what they can’t do anymore is prevent transmission.”
That’s why the CDC changed its guidance last week and is now recommending even vaccinated people wear masks indoors again, Walensky said.
“Last week, the agency released a study that showed the Delta variant produced similar amounts of virus in vaccinated and unvaccinated people if they got infected – data that suggests vaccinated people who get a breakthrough infection could have a similar tendency to spread the virus as the unvaccinated.”

The clinical trials showed that the mRNA vaccines were 95% effective at preventing SYMPTOMATIC COVID-19 (compared to the Placebo unvaccinated) and the 5% who were infected were virtually ALL NOT SEVERE.
Subsequent studies showed that full mRNA vaccination PREVENTED 90% OF DETECTABLE COVID-19 INFECTIONS compared to an equivalent group of UNvaccinated individuals. If the virus is UNDETECTABLE it’s NOT INFECTIOUS. Yes, the 10% of vaccinated who can have a breakthrough case (usually asymptomatic or, at most, mild) can be infectious but that would be a VERY SMALL NUMBER OF TEMPORARILY PERSONS compared to a much larger group of unvaccinated individuals.
