Since the invention of the first smallpox vaccine more than two centuries ago, there has been much controversy about the morality, ethics, effectiveness and safety of vaccination and 'immunization. There has been recent discussion about whether it is appropriate to introduce laws that reduce some or all required vaccines for all children. Parents, doctors, nurses, teachers and children all have an important role in this issue. Parents, of course, argue that they have the final right to decide whether or not to vaccinate their children. Nurses and doctors disagree with this view because by making vaccination rates incomplete in children, the risk of exposing children to vaccine-preventable diseases is greater. If this is a risk that some parents are willing to take, but others are reluctant to take, there is something to discuss. Every parent is worried about their child's health. However, this concern can take several directions. While some parents are convinced that vaccines were invented to prevent diseases transmitted from human to human, which could otherwise have serious health consequences for children and adults, other parents are certain that the vaccines themselves pose a health risk of their children. Health. Both have reasons to believe in what they do. It is known that since vaccines against diseases such as diphtheria and measles were introduced in the 20th century, the number of deaths related to these diseases has decreased by more than 500%1. On the other hand, the mid-20th century was also the period in which aspects such as nutrition, sanitation and health care, as well as other important factors in the spread of vaccine-preventable diseases, were significantly improved . It is difficult to determine precisely ... ... middle of paper ... ...that it is the right of a particular public or private school to decide whether or not to accept an unvaccinated child but at the same time the parents should be considered other parents and of their children, and get vaccinated to prevent others from getting sick, especially at school. Today vaccination is used all over the world and it is necessary to think about some standards so that all vaccines remain effective and pose minimal risk. If a child is not vaccinated, or has not been ill recently, has a healthy immune system and is vaccinated with a quality product, the risk of having undesirable consequences is less than 1%. The use of health protection from immunization is many times greater, which in my opinion makes the risk reasonable. Therefore, parents should vaccinate their children for the sake of their children and those around them.
