Reply to comment by Milk_Man21 in Cancer vaccines are showing promise. Here’s how they work. by nastratin

No it’s not possible in eukaryotic organisms that’s not how the immune system works. Immune memory is part of a selection process of reactive cells. mRNA vaccines work by having cells near the injection site temporarily express a foreign protein that the immune cells don’t recognize as “self” and then form a response against. Oddly enough, that IS how some bacterial immune systems work and is the basis of the endogenous bacterial CRISPR system that we now use to edit human cells.

Yup, the immune system need to learn “self” before it can learn “non-self”, so I imagine if you constitutively expressed these vaccines, your rate of cancer would increase.
