Oh, I know that MRna is not new & has been used quite successfully within Oncology as well from what I understand. I was meaning to say that the manner in which the vaccine was created & the entire process it went through prior to public release and all - was much much quicker than normal. I believe on average it's normally and approximately about a 10 year process, which was cut down to less than a year this go 'round. But I will easily defer to you about vaccines and the things you listed, which I honestly don't know a ton about.
