Why did the mRNA technology remain unapproved for a long time since its inception?<p>What exactly was relaxed in the approval process that lead to its EUA?<p>Since the vaccine has been used population wide, will the missed studies or what ever due process eventually be done? Or will they be skipped, citing the real world usage (which was not controlled or followed up in a systematic manner)?<p>Also, these people suffered adverse events in trials, and I think everyone who is thankful for the vaccines should try to get some help to these people.<p><a href="https://www.youtube.com/watch?v=6mxqC9SiRh8" rel="nofollow">https://www.youtube.com/watch?v=6mxqC9SiRh8</a>
