Yes it’s a serious issue. It’s clearly the same “ type “ vaccine. I’ve posted two long term of the studies related to mRNA vaccines , if you want to discount them that is your prerogative.
Im pretty sure I said none made through the animal testing stage, a long established protocol. This stage can take years to flesh out, but I’m sure you know this. If you want to parse words and not look at the spirt of what was said whatever. I stand by the statement, “ no mRNA vaccine has made to though the animal testing phase”, current vaccines included ( now they may but we don’t know yet because they effectively skipped the step altogether by the fast track process). The challenges often come when one is re-introduced to a mutated form of the virus( all virus mutate) , this takes time. Clearly this was not done but roll w whatever you like.
btw , I was kind of pissed hearing the Marvelous One died and made an Instructive statement to Moz while emotional. He is a big boy and we have enough history I suspect he didn’t take it the wrong way, but that’s between us.
