they were researching the mRNA technique for a long time to treat cancer, so it was expected the technique would make a fuckton of money that way. there wasn't so much interest in using it for infectious disease afaik, until this happened. vaccines typically don't make much money. take for example the Lyme vaccine, so many antivax idiots sued them that it isn't available anymore. your dog can get one, but not you. because of course soaking yourself head to toe in DEET is a totally harmless alternative.
