mRNA would be a nice capability to have, if it doesn't kill people or cause excessive side effects.
It looks like the side effects from mRNA vaccines are bigger than a typical vaccination. It's starting to look like mRNA vaccines may not be the vaccine you'd want in the long term based on this alone. The question is, do they create high severity side effects that preclude using them in the short term? We're about to learn...
There's a lot of other efforts; adenovirus vectors, attenuated efforts, non-replicating virus efforts. Of course, the adenovirus vectors are of concern because if immunity wears off, you can't necessarily give someone a booster a couple years later.
