Where vaccinations come into play the most is when you are looking at more dangerous diseases like Hepatitis B. According to the article Vaccine Preventable Childhood Diseases from the Illinois Immunization Program website below the Illinois Department of Public Health “ Hepatitis B, a liver infection that can become serious. It spreads through contact with blood or other body fluids. This can happen by sharing a razor, toothbrush, or needles to inject drugs, or through sexual contact. Hepatitis B causes a flu-like illness with loss of appetite, nausea, vomiting, rash, joint pain, and jaundice (yellowing of the eyes and skin). An infected pregnant woman can expose her newborn to this virus during childbirth. The virus remains in the liver of some people for the rest of their lives and can cause serious liver disease or cancer. Three doses of a new vaccine offer protection, and immunization is recommended for all infants, children and adolescents. Some adults who are at greater risk – doctors, nurses, teachers, paramedics, police officers – may need to be vaccinated” (Vaccine Preventable Childhood Diseases). When looking at the effects of Hepatitis B, they are quite scary and should not be viewed lightly. Vaccination against this disease is essential for young people as even today this disease can cause many fatal diseases.
