In 2011, Cuba developed CIMAvax, which remains the world’s only approved lung cancer vaccine. This vaccine works to induce the immune system to stop the growth of cancer cells and slow the progression of tumors. This vaccine has already treated more than 5,000 people across the world and many more thousands in Cuba itself. Given the immense significance of the vaccine, the United States agreed to a special arrangement to trial the vaccine in the US. The Roswell Park Cancer Institute in New York has been running clinical trials with CIM since 2018. They have run the first clinical trials of CIMAvax in the United States. The very same nation that is imposing a genocidal blockade on Cuba is also benefiting from the historic breakthroughs in healthcare.
