How Gene expression connects COVID19 vaccines to decades of science Through A Scientist's Eyes

How did normal cell biology let scientists come up with mRNA vaccines "so fast"...about 80 years of research went into these overnight vaccines.

These brand new vaccines are built an enormous amount of data on vaccines here are a few of the ones I read:
