Agreed.
The so called vaccine experts can't even answer an obvious question like; If people are vaccinated and become immune to Covid- 19, and later on come in contact with the virus, can they spread the virus to other people who are not immune, and haven' been vaccinated? -Tom
My common sense (which I have in tons) tells me that an virus infected person is not shooting streams of virus cells into the air unless coughing or sneezing or talking loud near you.
But virus cells could be present on his hands from previously scratching nose or touching mouth. So avoid shaking hands as much as possible. Even if you shake hands, virus can not penetrate tough skin on fingers but if you touch your contaminated fingers to your mouth or nose, the virus cell can enter your body.
At the end of day all depends on how many virus cells entered your body. If only a few, good chance your body will be able to kill them and acquire immunity in the process. That is the ideal situation to develop herd immunity.
