Cancer Immunization

There are possibilities of adverse reactions to vaccines due to presence of albumin or mercury, the possibility of vaccines containing live virus to actually cause the disease they are supposed to prevent (as in some forms of the polio vaccine), and other possible negative effects compared to the benefit of avoiding the disease. Appropriately applied statistics can help put the cost:benefit ratio into perspective. For example, if there is a family history of certain cancers, a vaccination may be warranted despite the risks. Because there are many types of cancers and vaccinations are highly specific treatments, one vaccination would not prevent most cancers, but only the type it was designed to prevent.
