One of the exciting things about mRNA vaccines is its relative simplicity and potential applications to other diseases, even outside of the realm of infectious diseases. Such as priming your immune system to better attack and eliminate tumors.
BioNTech, the co-inventor of the "Pfizer vaccine", just reported some very exciting data on pancreatic cancer, one of the very hardest-to-successfully-treat cancers that exists.
This blog report gives an accessible summary of the results and links to the study. Caveat: ONLY 16 patients, and 50% protection from disease re-occurance, where <10% is the norm. Obviously not a cure-all, but that difference, even with only 16 patients, is suggestive of a robust effect, for a disease that basically lacks effective treatments at the moment.
