8 Vaccination Schedules for Adults Often Overlooked

7. Meningococcal Vaccination - Risk-Based Adult Immunization

Meningococcal vaccination in adults requires a sophisticated risk-based approach that considers occupational exposures, travel destinations, underlying health conditions, and community outbreak situations that may not be immediately apparent to patients or healthcare providers. While routine meningococcal vaccination is primarily recommended for adolescents and young adults, specific adult populations face elevated risks that warrant immunization with either meningococcal conjugate vaccines (MenACWY) or serogroup B meningococcal vaccines (MenB), depending on their risk profile. College students living in dormitories, military recruits, laboratory workers handling Neisseria meningitidis, travelers to areas with hyperendemic or epidemic meningococcal disease, and individuals with complement deficiencies or anatomical or functional asplenia require meningococcal vaccination following specific protocols. The emergence of serogroup B meningococcal disease outbreaks on college campuses has highlighted the importance of MenB vaccination for young adults, particularly those in close-contact settings, though awareness and uptake remain suboptimal. Adults with HIV infection, complement component deficiencies, or those taking complement inhibitors face dramatically increased risk of invasive meningococcal disease and require both MenACWY and MenB vaccines with specific dosing schedules and booster recommendations. Travel medicine consultations often reveal adults planning trips to sub-Saharan Africa or other high-risk areas who are unaware of meningococcal vaccination requirements or recommendations, necessitating rapid immunization before departure. The severity of meningococcal disease, with case fatality rates of 10-15% and significant morbidity among survivors, underscores the importance of identifying and vaccinating at-risk adults before exposure occurs.
