Carefulness and practicality also become important when it comes to compulsory vaccinations. Why is it wise to immunize? What are the costs involved and how do you get vaccines to all people? How can public health policy work to the benefit of both those who have chosen to be vaccinated and those who oppose it? These are some of the questions that need to be answered and logistical scenarios need to be worked out. There are pros and cons to immunization, some who choose not to vaccinate themselves or their children do so not because they do not believe in immunization, but because they believe it should be their choice and not the government's choice to have their children vaccinated . It is important for families to make sure they comply with their state's immunization laws, and it is important for health care providers to be involved to help the family research and discuss vaccinations. This is necessary so that they can make it so that people can respond when told what to do and, if left to their own choice, might choose to immunize “48 vaccination requirements in state schools in the United States are less than mandatory allowing for philosophical beliefs/ personal or religious exemptions. Yet these laws have generally worked well to achieve and maintain relatively high levels of childhood vaccination coverage in the United States today.” (El Amin, Parra, Kim-Farley, & Fielding, 2012) The healthcare provider can greatly influence the decisions one may have about vaccination by using data-driven information to help better inform parents or an individual about vaccination and the pros and against vaccination. immunity. Addressing parental concerns about vaccine safety has a significant influence on decision makers and each parent should be provided with easily understandable information about the vaccine and possible side effects before the vaccine is administered.
