Cuba has had a vaccine for lung cancer since 2011, and now it's making it's way to the US.

CimaVax, which is both a treatment AND vaccine for lung cancer, has been researched in Cuba for 25 years. It's been FREE to the public since 2011.

Just like with all international drugs, researchers will need to conduct clinical trials, as well as replicate results before it becomes available to the public in the US.

Doctors say that the reviews from clinical trials in Cuba and Europe are "striking."

Another crazy part of this is how cheap it is! It cost the Cuban government only $1, and studies have shown that there is no significant side effects.

Oh yeah, it might work on more than just lung cancer...Here's what Dr. Kelvin Lee, Jacobs Family Chair in Immunology and co-leader of the Tumor Immunology and Immunotherapy Program at Roswell Park Cancer Institute in Buffalo, New York, the research center that is evaluating CimaVax for U.S. use, had to say:

"We think it may be an effective way to prevent cancer from developing or recurring, so that’s where a lot of our team’s excitement comes in," Lee said. "There’s good reason to believe that this vaccine may be effective in both treating and preventing several types of cancer, including not only lung but breast, colorectal, head-and-neck, prostate and ovarian cancers, so the potential positive impact of this approach could be enormous."

The entire article is a very interesting read, and includes how CimaVax works, how Cuba was able to pioneer it, and more!
