You sound overly paranoid no offense. Vaccines are meant to protect people from diseases , nothing else. By not vaccinating people, there is a risk of an outbreak of Polio or other diseases which dosent exist when the whole population is vaccinated. Its just too much of a risk because when people stop getting vaccinated, the disease has a chance to infect people who will transfer the disease to others that aren't. Personally Id rather get vaccinated then risk contracting a disease. No one wants these illnesses, they can kill people. There is a reason people have to get vaccinated. Because it dosen't just affect you, it's for everyone's health and safety.
