Yeah, lots of problems with mRNA vaccines in the past, including lots of deaths but it should be noted that those were animal studies (don’t tell PETA), not human studies. I couldn’t find any time frame for when the condition occurred after dosing but maybe it’s in one of the tables. So far, I don’t think we’ve heard of this happening in humans with these current vaccines. But this may also be a reason why they require 2 doses - they may have cut the dose back a lot from the earlier mRNA type vaccines.
But on whole I am suspicious, or skeptical, of the whole enterprise. I am suspicious how something that failed for 15 years suddenly works for this. I am suspicious that we threw billions into these vaccines and spent virtually nothing looking for treatments even when we had lots of evidence that HCQ+ and Ivermectin+ might work instead of running large trials they literally tried to “debunk” them. I am suspicious that Fauci et al have their own biases and wanted to advance mRNA technology and intentionally held back research into treatments to promote the mRNA platform.
