Re: Typical republican conservative bullshit.
Uh - the US and the rest of the world also has cancer vaccines. For a tiny handful of very specific cancers. They've been available for years, and are cheap. This is not news.
Your blanket statement that "Cuba has a vaccine for cancer," however, is a gross distortion of reality, making it seem as though a vaccine exists that prevents all cancer. And frankly, I'm being kind referring to it as a distortion; in actuality, it is far more likely to be a flat-out lie on your part.
BTW - Cuba has had a very serious problem over the last few decades retaining their own medical personnel. They were sending them overseas, mainly to south and central america, to train doctors in those regions, and once they hit the ground outside of Cuba they never came back. Most of them, in fact, made a beeline for the US.
