If you live outside of the city, maybe in the countryside or in the forest with your family, growing up building your immune system far away from pollutants and other people's diseases, I could then not understand why you would, with proper nutrition, not be able to build a perfect and strong immune system with time without the need for any 'vaccines'.
The natural, self evident, way of bringing up kids should be promoted, getting people back out into farming and self sufficiency, not promote dependence on governments in the city, requiring people to adapt to a life that never suited humans, something that gradually devolved into housing for slaves to the (((banking system))).
