71750 As from the year 1995, CDC in conjunction with American Academy of Family Physicians (AAFP) and American Academy of Pediatrics (AAP) has always put emphasis on annual childhood immunization schedule. Prior to this year, these groups updated the immunization schedule only once in a while. The first vaccines were: Smallpox, tetanus, diphtheria, and pertussis. hepatitis B and Haemophilus influenza type were introduced in the 19870s (The Children’s Hospital of Philadelphia, 2014). The first formal vaccination for adults was introduced in the year 2002. According to the state of Ohio, a child who presents a written disapproval of immunization for conscience reasons would not be expected to be immunized. This is an indication that parents say is always final to the immunization of their children (Centers for Disease Control and Prevention (CDC), 2014). Otherwise, all the other children are supposed to be immunized in accordance with the most recent version of the recommended vaccine. When a child is humanized with a certain disease, it does not only protect them but also protect the other children around them. This is because they would not be able to spread the diseases because their bodies will be able to stand the attack. Immunization also helps in preventing lifelong suffering. Some diseases such as polio can lead to loss of body parts which means that the affected persons will have to live without those body parts for the rest of their lives. As compared to treatment, vaccination is usually safe. .
