Haemophilus influenzae Type b (Hib) Vaccine Universal immunization for children aged <5 years High-risk indications for persons aged ≥5 years Immune system disorders
Meningococcal Vaccine Not universal immunization High-risk indications usually for persons aged ≥2 years Travel to endemic country Outbreak control College Freshman living in dorm (often optional) Immune system disorders
Pneumococcal Polysaccharide Vaccine (PPV23) Universal immunization for adults aged ≥65 years High-risk indications for persons aged 2-64 years Immune system disorders Residence in special environments or social settings Chronic medical conditions
Chronic Medical Conditions with PPV23 Indication Cardiovascular disease Pulmonary disease (not asthma) Diabetes mellitus Alcoholism Chronic liver disease Cerebrospinal fluid (CSF) leaks
Pneumococcal Conjugate Vaccine (PCV7) Universal immunization for children aged <2 years High-risk indications for children aged 2-4 years Moderate-risk considerations for children aged 2-4 years
PCV7 High-Risk Indications Children Aged <5 Years Immune system disorders Chronic medical conditions Similar to PPV23, including CSF leaks
PCV7 Vaccine Supply National Vaccine Shortage
Public Health Response Meningitis Vaccination and Cochlear Implant Recipients Reviewed meningitis vaccination recommendations Disseminated vaccination information to stakeholders Cochlear implant recipients State health departments Health care providers
Immunization Response to Cochlear Implants and Meningitis Association Could vaccination decrease the risk of meningitis among cochlear implant recipients?
Review of Vaccination Policy Vaccine-preventable cause? Yes, pneumococcus Biological plausibility? Yes, potential anatomic pathways and other mechanisms
Review of Vaccination Policy Applicable ACIP high-risk indication? Yes, pneumococcal vaccination for persons with CSF leaks Accessibility concerns? Yes, national PCV7 vaccine shortage
CDC Recommendation for Cochlear Implant Recipients: High-Risk Pneumococcal Vaccination

Vaccination for Cochlear Implant Recipients Four bacterial meningitis vaccines covering three causes of meningitis No initial specific vaccination recommendations Current pneumococcal vaccination recommendations Following study need to reevaluate vaccination recommendations
