Vaccine Hesitancy: Resources & Information

From the moment babies are born, they are exposed to numerous bacteria and viruses on a daily basis. Eating food introduces new bacteria into the body; numerous bacteria live in the mouth and nose; and an infant places their hands or other objects in their mouth hundreds of times every hour, exposing the immune system to still more antigens. When a child breathes in one of the many cold viruses, they are exposed to at least 4–10 antigens and exposure to “strep throat” is about 25–50 antigens.
