Sounds promising,NOT.
Pretty exciting stuff. Immunotherapy from mRNA is probably the only real path we have to curing all cancers.
1) Get the genome of the cancer cell
2) Get it into an mRNA vaccine
3) Get our immune system to destroy the cancer
All of these are technologies that exist and we understand, but a lot of hard work to get it done.
Still there is a real chance that we are the last generation where cancer is an issue.
