What are the guidelines for revaccination with meningococcal conjugate vaccine (MCV) if a child has previously received meningococcal polysaccharide vaccine (MPSV)?
ACIP addressed this situation in their 2005 meningococcal recommendations, http://www.cdc.gov/mmwr/PDF/rr/rr5407.pdf [322KB – 28 pages] (page 15). Children should receive the recommended dose of MCV between the ages of 11-18 years once 5 years have elapsed since the MPSV dose. If a high-risk situation exists, the child can receive the MCV dose sooner as long as at least 2-3 years have elapsed since the MPSV dose. There are no recommendations for revaccination following a dose of MCV.
