After 30 years of painstaking research mRNA technology allowed several groups of scientists — including a group at Pfizer working with a German company called BioNTech, and a young company in Massachusetts called Moderna — to bring mRNA vaccine technology to the threshold of actually working.

The companies had built platforms that, theoretically, could be used to create a vaccine for any infectious disease simply by inserting the right mRNA sequence for that disease.

The lipid nanoparticle was the final breakthrough to allow such a vaccine to work.

Worth repeating :)

And, reminding folks that this technology will lead to a vaccine for every type of cancer.

I think you missed the word "theoretically."

Just like Windows ME is theoretically an operating system.

Ever hear of chimerism?
