A vaccine is a biological preparation that improves immunity to a particular disease. A vaccine typically contains an agent that resembles a disease-causing microorganism, and is often made from weakened or killed forms of the microbe, its toxins or one of its surface proteins. The agent stimulates the body's immune system to recognize the agent as foreign, destroy it, and "remember" it, so that the immune system can more easily recognize and destroy any of these microorganisms that it later encounters. (WHO)
The administration of vaccines is called vaccination. The effectiveness of vaccination has been widely studied and verified; for example, the influenza vaccine, the HPV vaccine, and the chicken pox vaccine. Vaccination is the most effective method of preventing infectious diseases; widespread immunity due to vaccination is largely responsible for the worldwide eradication of smallpox and the restriction of diseases such as polio, measles, and tetanus from much of the world. The World Health Organization (WHO) reports that licensed vaccines are currently available to prevent or contribute to the prevention and control of twenty-five infections. (Wikipedia)
And about Mesothelioma cancer, Researchers have highlighted the need for early testing and treatment options; one of the newest is a vaccine that so far appears to be safe in humans and the use of immunotherapy, a promising new approach for treating various types of cancer.
Vaccine explored for mesothelioma that can extend the life of patients using their own dendritic cells (DC) and tumor antigen. The vaccine is needed even though asbestos has been banned for decades because cancer can develop 50 years after exposure.
The diagnosis of mesothelioma is usually followed by death within one year, and chemotherapy adds less than six months for the survival time.
A vaccine for mesothelioma, can prolong life and protect those affected by producing immunity against cancer is very harmful to the lungs and other organs.
mesothelial tissue present in the lungs and abdominal cavity (peritoneum), and also includes the heart (pericardium). Cancer is most often starts in the lungs or abdomen. According to the National Cancer Institute there are 2,000 new cases of the disease are diagnosed in the US every year.
Mesothelioma vaccine research published in the American Thoracic Society's American Journal of Respiratory and Critical Care Medicine, March 2010. A drawback of producing a vaccine is that mesothelioma suppress immunity, interfere with immunotherapy - a problem that researchers are trying to solve.
