It’s been over four years since the Advisory Committee on Immunization Practices (ACIP) influenza vaccine recommendations were expanded to include six-23-month-olds, and two years since the recommended expansion for 24-59-month-olds. So how diligent have pediatricians and family medicine (FM) docs been in applying these recommendations? A study by researchers at the University of Colorado, Denver School of Medicine, found that adherence among pediatricians has been almost universal, with family medicine docs trailing behind. Using responses to e-mail and mailed surveys, researchers found that 95% of peds surveyed routinely vaccinated six-23 month olds for the flu, with only 72% of FM docs routinely vaccinating patients in this age group. Surprisingly, in the 24-59 month old age group, adherence among peds was 80%, with only 42% of FM docs vaccinating this group.
