I was reading up on some different degrees, and came across Immunology and Molecular Virology and Microbiology at the school I was interested in. What's the difference between these? I'm interested in creating medicine and vaccines, so which of these would be more beneficial for that

I have a rare auto immune diseas (Microscopic Polyangitis), caused small intestine to have two lots of surgery, arthritis, premature osteoporosis, heart murmur, kidney failure and consequent kidney transplant......I would like to leave my shell to medical science - what do I have to do to achieve this? Just tell my Doctor, or is there something else I have to do? I am certin it will be very useful - medical teams get very excited qand interested when they have to take care of me!! Any ideas
