Cuba Has A Lung Cancer Vaccine, And Now It Could Be Coming To The USA "Cuba launched the world's first lung cancer vaccine, Cimavax, to the public back in 2011. Each shot costs about $1, but the Cuban government has made the vaccine available to the public for free. Now it's 2015, and other countries are starting to get curious and want to get their hands on it too."
The vaccine contains a protein called epidermal growth factor (EGF). EGF, which stimulates the growth of cells, is found naturally in the body, but cancerous tumors can stimulate the body into producing too much of this protein. This causes the tumor to multiply and grow uncontrollably.
When vaccinated, EGF, among other compounds, enters the bloodstream of the patient and encourages the immune system to produce antibodies that suppress the effects of EGF. This prevents tumors from getting bigger, but doesn't directly attack them.
This vaccine is given to people who already have lung cancer. It isn't like a measles vaccine that is given to an infant who can then expect never to suffer from the disease. Known as a therapeutic vaccine, it is given to patients who already have cancerous tumors in their lungs. Cimavax inhibits their growth and stops them from spreading, or metastasizing, to other parts of the body, which makes treatment significantly more difficult.
