Cuba’s Groundbreaking Cancer Vaccine Treats More Than 100,000 Patients
Nearly 20 years ago, a number of researchers at the Center of Molecular Immunology in Havana, Cuba, have invented a vaccine, called CimaVax, which can successfully treat lung cancer. According to the researchers, even though this vaccine is currently licensed only for lung cancer, it could be used for other types of cancer as well, including breast, colon, prostate, and pancreatic cancer.
In 2015, the vaccine was tested on 9,000 people, and, to date, it has cured more than 100,000 cancer patients, without any radiation, chemotherapy, or surgery.
How Does the CimaVax Vaccine Work?
The CimaVax Vaccine targets a particular protein, known as epidermal growth factor (EGF), which naturally occurs in the body. EGF sends signals to the cells to grow and divide by attaching to a receptor protein on the surface of the cells.
Some types of cancer encourage the body to produce too much EGF in order for the cells to grow and divide uncontrollably. The vaccine stimulates the immune response of the body. It helps the body to produce antibodies which are able to recognize and to bind to the EGF.
This prevents the EGF from attaching to the receptors on the cancer cells. Therefore, the growth of the cancer slows down because there is no signal urging the cancer cells to grow and divide.
The CimaVax vaccine is used as a cancer treatment, rather than as a preventive measure. It is given to patients who are already dealing with lung cancer in order to prevent the cancer cells from spreading and metastasizing to other parts of the body.
Even though the vaccine is licensed only for lung cancer, the researchers are optimistic that it could be used for treating various other types of cancer because the signaling of the epidermal growth factor doesn’t stimulate only the development of lung tumors, but it also plays a role in colon, breast, prostate, and pancreatic cancer.
Apart from Cuba, the vaccine can be legally purchased in Colombia, Peru, Paraguay, as well as Bosnia and Herzegovina. After the visit of Barack Obama in Cuba in November 2016, the vaccine is also being tested in the US laboratories.
The entire treatment lasts for about 8 months and costs approximately 10,000 US dollars. The patients who don’t have such resources are advised to go to Cuba in order to receive the first few doses of the vaccine and instructions for the treatment.
The first two doses of the vaccine are injected in the hand, and the second two in the leg. The rest of the treatment can be performed at home. The price of the CimaVax vaccine in Cuba is $100.
