QUESTION: If someone is older than 55 years and had their spleen removed, are they recommended for meningococcal polysaccharide vaccine or meningococcal conjugate vaccine?
ANSWER: Meningococcal conjugate vaccines (MCV4) are licensed for persons through age 55 years. For persons older than 55 years with a high-risk medical condition (such as asplenia), the Advisory Committee on Immunization Practices (ACIP) recommends off-label use of MCV4. Asplenic persons should receive a primary series of two doses of MCV4 separated by eight weeks, followed by a dose every five years thereafter. These recommendations are available at www.cdc.gov/mmwr/pdf/rr/rr6202.pdf, page 15.
