Which of the following scenarios is an appropriate shared clinical decision-making for meningococcal vaccine?

The scenario involving a healthy 16-year-old who received the meningococcal B vaccine is a good example of appropriate shared clinical decision-making regarding vaccination. This age group is typically considered for routine vaccination against meningococcal disease, particularly the MenACWY vaccine and MenB vaccine, depending on individual risk factors and preferences.

In this case, immunization against meningococcal B is recommended for healthy adolescents, especially since this group is at higher risk for infections due to close contact in communal settings like schools. The decision to vaccinate is supported by guidelines that promote vaccination in healthy adolescents, allowing for a collaborative decision between the healthcare provider and the patient or the patient's guardian regarding the benefits and potential risks of the vaccine.

The other scenarios presented involve specific medical conditions or contexts that may not align with the standard recommendations for shared decision-making in a healthy adolescent. For instance, adults or children with underlying health conditions such as asplenia or complement deficiency require tailored vaccine recommendations based on their increased risk for invasive meningococcal disease. While these decisions are still important, the context of shared decision-making is more straightforward and applicable when considering the healthy adolescent population and the routine vaccination schedule.
