The health risks for the J&J weren’t trumped up but probably was forced off the market by the competition like you say.
J&J was just as problematic as the mRNA’s.
“How Bad Is My Batch” showed my batch had a 1.4% published fatality rate. I almost joined that group but just ended up with almost every othe adverse reaction listed and one more not listed. I did suffer a lot. Three years later I’m a lot better but still fighting it.
See the discussion of J&J at my above link.
I took two rounds of J&J, had a bit of reaction to the second shot, but nothing out of line from some other vaccines I’ve gotten over the years, Never got Covid that I know of, and didn’t hide out from the public. (Went shopping during the “crisis”, went to church as soon as they reopened after the ‘six weeks to save the world’, went back to the office as soon as it reopened, etc.
So I still contend that it was effective, was not as bad as the other two, and was sabotaged and then treated unfairly by the New World Order.
