Its aim is to protect individuals and communities from infectious diseases.
Immunization operates like an early warning system.
It prepares the body to fight against infection. How does immunization work Immunization operates on the premise that once you have had a disease, you are unlikely to contract it again. Through injections, oral drops or scratches on the skin, the body is exposed to weakened or dead disease-producing microorganisms or to the toxins they produce. This will cause the individual to develop the same antibodies and antitoxins that would have been developed if the person had actually contracted the disease, in order to fight the disease. Once the body has been exposed to an infection, the immune system will recognize if the disease were to recur, and produce antibodies or antitoxins to destroy the infection.
