Vaccinations are meant to help prevent disease for formatting inside the human body, but they aren't the cause of disease from happening. Not taking the vaccines is putting others at risk that have taken them,because they are only effective if someone cannot spread the diseases to them on a wide scale. Some parents don't want to give their children vaccinations because of cultural or religion reasons, or even because they don't believe that the disease can affect their child because it hasn't been seen happening often in years such as polio. They don't understand that diseases just don't go away, they lie dormant until they can infect someone to help spread it again. This is why schools require all of the students to have their vaccinations
