Rabid defense of the "vaccine" that is obviously not effective, and actually causes disease and death, is usually due to either:
1. One who received the shot, and is afraid to face reality.
2. One who is considered an expert in some way (his case) and is told to push the party line.
3. A person who works in healthcare, and cannot afford to say anything against the shot, for fear of losing their job.

I would bet the farm, depending upon where I was at the time, my employer(s) would never have said 'Get the vax or lose your job!' I never signed anything saying my employment informed me that I had to take an experimental vaccine'. This is a bunch of B.S. And blood tests will show you have the antibodies from the virus or the disease but the lab's can't differentiate. I know that for a proven fact. My blood tests show the antibodies because I had covid, but the hospital couldn't tell if I'd been vaxed! There should be some class action suits on this topic. And as for children dying, I do believe there is a law (tried in the Supreme Court protecting children against forcible vaccines. It was put in when children were being required to take Polio vaxes and the polio vaccine got contaminated.
