Didn’t Cuba have a vaccine for lung cancer? I seem to recall seeing one in a documentary (maybe a Michael Moore film?)
> I also ran a failed medical tourism company which sent people to get this treatment in Cuba
Why did the company fail? How effective was the treatment?
There was also a published study by Roswell Park, on a few hundred patients many of which flew out to Cuba to take it, but it's only Phase 1, so no efficacy, only safety and antibody titers : https://www.roswellpark.org/newsroom/201903-safety-analysis-...
After observational studies of patients who flew to Cuba to take it confirmed efficacy, phase 2 clinical trials are underway in the US : NCT02955290
It's unfortunate it took this long. If it wasn't for the sanctions, it would certainly already have either finished (or failed, though unlikely) trials.
