A nurse is providing education to the caregiver of a school-age child regarding immunizations to prevent respiratory infections. Which of the following information should the nurse include in the teaching?

A. Children with chronic respiratory conditions, such as asthma or cystic fibrosis, are actually recommended to receive vaccines to prevent respiratory infections. Vaccinations help reduce the risk of complications from illnesses like influenza or pneumococcal disease. Avoiding vaccines would increase their risk of severe infection. B. Immunizations are most effective when administered according to recommended schedules, often starting in infancy and continuing through school age. Early immunization helps protect children before they are exposed to serious pathogens, preventing respiratory infections such as influenza, pertussis, and pneumococcal disease. C. Many vaccines require multiple doses or booster shots to achieve full immunity. For example, diphtheria, tetanus, pertussis (DTaP), and pneumococcal vaccines often require a primary series followed by boosters. Stating that most vaccines require only one dose is misleading. D. Currently, there is no vaccine available for the rhinovirus, which causes the common cold. Preventive strategies include hand hygiene, respiratory etiquette, and avoiding exposure, rather than vaccination.
