good luck guys! I tried crowdfunding for biomedical research (preclinical) and I learned a lot about crowdfunding in the process - will be restarting later this year, I hope to learn from your success. With some knowledge about the AIDS vaccine field (had many colleagues in that space in grad school, attended many talks) I think your project is really worthy and a fresh approach. I also volunteer weekly for an AIDS-related nonprofit, so this is a personal issue for me, I have seen clients of mine pass away of AIDS. I'll definitely be chipping in myself.
