> We do not have a similar level of understanding for the mRNA type. And yet we are pushing it out at a never seen before scale and speed. It's my understanding that the Pfizer/BioNTech vaccine is the first vaccine that is demonstrably reliable, safe, and able to be mass produced. Mankind may have a track record with another kind of technology, but until someone is able to come up with a vaccine that is reliable, safe, and able to be mass produced, they will remain in the hypothetical territory. It's better to have a vaccine in the hand than two in the theoretical textbooks.
