Nobody claimed that all vaccines ever made have all been 100% safe and have never led to any adverse effects. Any common medical practice or procedure will occasionally result in adverse effects. That is not any kind of vindication for the conspiracy theorists who claimed that there was a sinister agenda behind the covid vaccine and that it would lead to widespread deaths, injuries, and sterility. It's been three years since the vaccine came out, and if it was supposed to do something bad to us, we would have taken effect by now, and on such a scale that it would be impossible not to recognize. Nothing of the sort happened. We're fine. Whatever bad thing the government might be planning for us, the covid vaccine simply wasn't it.
So vaccines are not 100% safe, but miraculously all the COVID-related ones are? I am claiming that no vaccine is safe and I stand by that claim. Believing there is a 100% safe vaccine out there is hopeful ignorance, and also unscientific.
And, you are dead wrong that they did no damage. But people are largely in denial that it was the vaccines that caused their medical problems (or death of loved ones, in some cases) and blame anything else instead, including COVID. Not everybody, though, which means you are unaware of what's going on.
Ok you're gonna have to explain how one can be 50% fertile. What, is half my sperm dead or something?
You're gonna have to do a sperm count test to know that one. It's also supposed to analyze the quality and not just the quantity.
Also, probably unrelated to fertility, but I would check for blood clots if I were you. Not medical advice, though.
