A<unk> is a vaccine which is administered after a disease or infection has already occurred. A<unk> works by activating the immune system of a patient to fight an infection. A<unk> differs from a prophylactic vaccine in that prophylactic vaccines are administered to individuals as a precautionary measure to avoid the infection or disease while<unk>  are administered after the individual is already affected by the disease or infection. A<unk> fights an existing infection in the body rather than immunizing the body for protection against future diseases and infections.<unk>  are mostly used against viral infections. Patients affected with chronic viral infections are administered with<unk> , as their immune system is not able to produce enough efficient antibodies. Provenge, developed by Dendreon, was the first<unk> approved by the FDA in 2010. This<unk> helped in treating prostate cancer where patients' own white blood cells (WBCs) were taken and treated with drug (vaccine) to train them to differentiate and fight cancer cells.
