Health is a state of complete physical, mental and social well-being and not merely the absence of disease or infirmity (WHO). Nowadays, this is one of the global issues that experts are trying to solve on how they can help each individual to attain this stage, which in the end they across of finding ways on how an individual will be able to achieve this goal.

When one gets immunized, the body develops the ability to fight off a given disease. Immunizations safeguard the body from illnesses and death caused by certain infectious diseases. Some immunizations are given to prevent a single disease, while others will take care of two or three diseases. Immunizations help control infectious diseases that were once common. They have reduced, and in many cases, eliminated, diseases that routinely killed or harmed infants, children, and adults. However, the viruses and bacteria that cause vaccine-preventable disease and death still exist and can be passed on to people who are not immunized. Children need immunizations to protect them from dangerous childhood diseases. How can this be possible for everybody? That was answered by World Health Organization, when they initiated the Expanded Program on Immunization in May 1974 with the objective to vaccinate children throughout the world. Ten years later, in 1984, the WHO established a standardized vaccination schedule for the original EPI vaccines: Bacillus Calmette-Guérin (BCG), diphtheria-tetanus-pertussis (DPT), oral polio, and measles. Increased knowledge of the immunologic factors of disease led to new vaccines being developed and added to the EPI’s list of recommended vaccines: Hepatitis B (HepB), yellow fever in countries endemic for the disease, and Haemophilus influenzae meningitis (Hib) conjugate vaccine in countries with high burden of...
