Inactivated Vaccine

An inactivated vaccine is a type of vaccine that uses a dead version of a virus or bacteria to prevent illness. By introducing a weakened version of the virus or bacteria into the body it is able to stimulate an immune response and develop immunity against the illness. Unlike live vaccines, which work by replicating inside the body and provoking an immune response, inactivated vaccines do not contain a live agent, thus reducing the risk of adverse reactions. Inactivated vaccines are widely used for a range of diseases, and are particularly important in providing protection against illnesses such as polio and hepatitis A.
