Phase 3 clinical trials already cost $50 million and have a 10% success rate. I don’t think anyone’s looking to dump even more money into a study that’s testing things not in question. And no matter the results, people who are anti-vaccine are going to make the same claims anyway.
I’ve seen claims that the vaccines contain space alien DNA, mind control microchips, poison, sterilizing agents, self-destructing time bombs, active SARS-CoV-2 virus, and all manner of other ridiculous nonsense. You think another study is going to help that? These people seriously think Bill Gates is controlling peoples’ brains through 5G towers with the shots.
You certainly sound very knowledgeable, and you screen name and tag line are convincing too.
