LOL, what are you talking about? You are taking something that someone said somewhere on TV land, and using that as the basis of your argument, or claim.
It was, and is, by all the data gathered thus far, from around the globe - clearly untrue.
And your link demonstrates what exactly? How ignorant some folks are? Do you really expect me to listen to a 50 minute podcast to determine something that I already know to be false? LOL
Even the title of that link clearly states: "those who have not been vaccinated, “Are going to get the Delta variant.”
COVID ‘Is Really That Contagious,’ Says Admiral Brett Giroir Regarding Delta Variant
The former Assistant Secretary for Health for the U.S. Department of Health and Human Services warns those who have not been vaccinated, “Are going to get the Delta variant.” Those who had COVID before do not have a guarantee of protection against the virus.
I would hope that it would be obvious by now, that only some people that are vaccinated x 2 will end up with breakthrough infections. If not, well it certainly should be. If you choose to believe only what you want to believe, that's on you.
