It was considered a dead end technology because it kept killing the test animals, and there's no evidence that the problems were resolved. But at least you can sue them if something goes wrong...oh wait, you had to give up that right before getting them. You absolute fucking retard.

How about you post a list of approved mrna treatments given to people from before 2019 and then the studies on their long term effects, that should be easier to find than internal lab results from big pharma. 

I tried using my search engine to find 'mrna treatments for humans before 2019' and couldn't find anything except for studies on animals being rejected during the challenge phase of testing.
