-I’m old enough to remember there was a lot of excitement about mRNA as a potential vaccine technology way back in the early 90’s. -
Don’t know anything about the 90s, but as far as I can, a lot of the thinking about the mRNA vaccine (or its invention) for these varieties of covids was a product of the Obama covid of 2012 which used up all of the governments ventilators & stuff (never restocked). All that was necessary to make the vaccine was the genetic information of Covid 19.
Well, yeah, kinda. The vaccines are a step back from the big ambition, but they still represent a major step forward.
