Immunity Project

Immunity Project was a San Francisco nonprofit and Y Combinator company (batch Winter 2014, one of YC's first non-profits alongside Watsi) that set out to develop a free HIV/AIDS vaccine. Its approach studied naturally immune "HIV controllers" and applied machine learning to reverse-engineer the immune response, aiming to deliver a crowdfunded, virus-free vaccine via nasal spray. Founders included Reid Rubsamen, Naveen Jain, and Ian Cinnamon. The organization surfaced in the API Evangelist network as a Y Combinator portfolio lead; enrichment found no developer portal, documentation, or API surface, and its former domain (immunityproject.org) has lapsed and now redirects to an unrelated third-party news outlet, indicating the project is effectively defunct.

Immunity Project is profiled on the APIs.io network. Tagged areas include Company, Non-Profit, Health Tech, Biotech, and HIV.

Regulatory Posture applies to this provider. Its tags matched the Health regime, so Regulatory Posture carries 15 points of the composite. If this regime is wrong for your business, say so on your provider repo — the applicability map is public and we will correct it.
The six quality facets above are damped to 85 points between them, because the conditional facet above carries the other 15. That is why each facet's contribution is shown against a damped maximum: raising a quality facet moves the composite by 85% of its nominal weight, not 100%. The full arithmetic is at apis.io/rating/.
Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/.
