Timing of Adolescent Meningococcal Conjugate Vaccination Attitudes and Practices of Pediatricians and Family Medicine Physicians

Background The meningococcal conjugate vaccine (MCV4) was recommended for those aged 11–18 years in 2005. Initial supply issues led to an emphasis on immunizing older adolescents. When supply improved in 2007, routine immunization was recommended for those aged 11–12 years. Purpose Among a U.S. sample of pediatricians and family medicine physicians, describe (1) recommendation and administration practices for MCV4; (2) preferences regarding MCV4 administration; and (3) attitudes and characteristics associated with recommendation for those aged >12 years. Methods A mail and Internet survey in a nationally representative sample of physicians was conducted between December 2009 and March 2010. Analysis was conducted between March 2010 and October 2010, including a multivariable analysis to examine factors associated with deferring MCV4 to ages >12 years. Results Response rates were 88% (pediatricians 367/419) and 63% (family medicine physicians 268/423). In all, 95% of pediatricians and 73% of family medicine physicians reported administering MCV4 routinely to those aged 11–18 years ( p p 12 years ( p Conclusions Most pediatricians and family medicine physicians administer MCV4, but many, especially family medicine physicians and those concerned about waning immunity, defer their recommendation for MCV4 to patients aged >12 years.
