We all know that it is important to get kids vaccinated but do we really know how vaccination works? However, you can know it from expert, Dr. Keller Wortham, how vaccination works in protecting your baby from various deadly disease. Immunization refers to the process where a person is made immune from an infectious disease through the use of vaccine. Vaccine therefore, contains germs that have either been killed or weakened. These germs trigger the immune system to respond to the injected virus (the disease causing organism), thus building immunity.
Dr. Keller Wortham, also said that the concept of immunization was inverted by a British doctor, Dr. Edward Jenner, in 1796. He noticed that cattle workers who were infected with a harmless disease called Calpox, seemed to be protected from smallpox. Smallpox affected major parts of the United Kingdom at that time. He found that purposely infecting humans with Calpox can immune them against smallpox. Dr. Edward Jenner then named this process vaccination.
Dr. Keller Wortham further said that the disease causing organisms can have two effects on our body. First, they make us sick and cause fever, nausea, vomiting, diarrhoea, and rash among others. And the other effect improves and strengthens our immune system. According to him, disease causing organisms contain protein called antigens (foreign toxin). To fight this foreign substance, our white blood cells create anti-bodies which bind the antigens. After the first time, the body creates memory cells to look out for this antigen. If the antigen returns, the memory cells create tons of antibodies to prevent the infection it may cause. Hence, vaccines act in a manner that safe-guard human against disease causing organisms and the process of achieving this is through VACCINATION.
