Haemophilus influenzae Type b (Hib) Vaccine
• Universal immunization for children aged <5 years
• High-risk indications for persons aged ≥5 years – Immune system disorders
![Page 6: Bacterial Meningitis Vaccines and the Prevention of Meningitis in Cochlear Implant Recipients Karen Broder, M.D. Epidemic Intelligence Service Officer](https://reader033.vdocuments.site/reader033/viewer/2022052618/5514d1ca55034693478b4fed/html5/thumbnails/6.jpg)
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
![Page 7: Bacterial Meningitis Vaccines and the Prevention of Meningitis in Cochlear Implant Recipients Karen Broder, M.D. Epidemic Intelligence Service Officer](https://reader033.vdocuments.site/reader033/viewer/2022052618/5514d1ca55034693478b4fed/html5/thumbnails/7.jpg)

![Page 10: Bacterial Meningitis Vaccines and the Prevention of Meningitis in Cochlear Implant Recipients Karen Broder, M.D. Epidemic Intelligence Service Officer](https://reader033.vdocuments.site/reader033/viewer/2022052618/5514d1ca55034693478b4fed/html5/thumbnails/10.jpg)
PCV7 High-Risk Indications Children Aged <5 Years
• Immune system disorders
• Chronic medical conditions
– Similar to PPV23, including CSF leaks

Public Health ResponseMeningitis Vaccination and Cochlear
Implant Recipients
• Reviewed meningitis vaccination recommendations
• Disseminated vaccination information to stakeholders– Cochlear implant recipients– State health departments– Health care providers
![Page 13: Bacterial Meningitis Vaccines and the Prevention of Meningitis in Cochlear Implant Recipients Karen Broder, M.D. Epidemic Intelligence Service Officer](https://reader033.vdocuments.site/reader033/viewer/2022052618/5514d1ca55034693478b4fed/html5/thumbnails/13.jpg)
Immunization Response to Cochlear Implants and Meningitis Association
• Could vaccination decrease the risk of meningitis among cochlear implant recipients?
![Page 14: Bacterial Meningitis Vaccines and the Prevention of Meningitis in Cochlear Implant Recipients Karen Broder, M.D. Epidemic Intelligence Service Officer](https://reader033.vdocuments.site/reader033/viewer/2022052618/5514d1ca55034693478b4fed/html5/thumbnails/14.jpg)
Review of Vaccination Policy
• Vaccine-preventable cause?– Yes, pneumococcus
• Biological plausibility?– Yes, potential anatomic pathways and
other mechanisms
![Page 15: Bacterial Meningitis Vaccines and the Prevention of Meningitis in Cochlear Implant Recipients Karen Broder, M.D. Epidemic Intelligence Service Officer](https://reader033.vdocuments.site/reader033/viewer/2022052618/5514d1ca55034693478b4fed/html5/thumbnails/15.jpg)
Review of Vaccination Policy
• Applicable ACIP high-risk indication?– Yes, pneumococcal vaccination for
persons with CSF leaks
• Accessibility concerns? – Yes, national PCV7 vaccine shortage

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
