As US government regulated restrictions around Cuba slowly ease, a few things have come to light. One being that Cuba hosts some of the world’s leading biotech and medical research. Now, the US is looking to bring a promising lung cancer vaccine from the Caribbean nation stateside. Called Civamax, the vaccination spurs the body into releasing antibodies that can prevent lung tumors from metastasizing, making them more manageable. The US is hoping to further develop Civamax into a formidable defense in the battle against lung cancer.
