A community health nurse is conducting an in-service program for a group of nurses working at the local health clinics about immunizations and disease prevention.

Question

Quizplus · Accepted Answer

There is no evidence that the vaccine-preventable disease causative organisms have increased virulence. The following issues motivated the increased doses of certain vaccines and reformulated vaccines at the start of the 19st century. Pertussis immunity was found to wane with age so the vaccine was reformulated to cocoon infants by immunizing the adults around them to prevent exposure of infants; varicella vaccine given in two doses has been found to increase immunity, and measles outbreaks were identified in populations where parents had refused MMR vaccination for their children and received personal belief exemptions.
