VAIL, Colo. – Never underestimate the power of a physician’s strong personal recommendation of a vaccine in influencing a parental decision to get their child vaccinated and perhaps themselves as well.

“It has been shown time and time again in multiple studies that one of the most critical factors in parents’ acceptance of vaccines either for themselves or for their child is a personal physician recommendation for that vaccine,” Dr. Marsha Anderson said at a conference on pediatric infectious diseases sponsored by the Children’s Hospital, Denver.
This point has been brought home in studies involving several different vaccines, most recently in a national survey regarding uptake of the 2009 monovalent vaccine against pandemic H1N1 influenza, noted Dr. Anderson, a pediatric infectious disease specialist at the hospital and the University of Colorado.
The C.S. Mott Children’s Hospital National Poll on Children’s Health conducted a national survey of H1N1 vaccination rates as of January 2010. The survey, conducted by professional pollsters on behalf of the hospital, which is a part of the University of Michigan Health System, included a nationally representative sample of 2,246 adults. The results showed that as of last January, 29% of children and 16% of adults had received the pandemic H1N1 vaccine.
Among the 38% of survey participants who reported that their child’s health care provider strongly recommended the vaccine, the vaccination rate was 66% in their children and 57% among the parents themselves.
With less emphatic endorsements by the physician or another health care provider, vaccine uptake rates fell off sharply. For example, when parents reported that their child’s health care provider “somewhat” rather than “strongly” recommended the H1N1 vaccine, the vaccination rate was 30% for their children and 19% for the adults.
And when the health care provider was seen as “neither for nor against” the H1N1 vaccine, as was the case for the physicians of 35% of the children and 55% the adults, the vaccine uptake rate plunged to 11% among the kids and 7% for adults.
When Dr. Anderson polled her Vail audience, comprised mainly of general pediatricians and family physicians, as to how frequently they experienced frustrating conversations with “vaccinophobic” parents regarding immunizing their children, 35% indicated it happened at least once per day on average, and another 37% said it occurred 3-4 times per week. So this is an issue that commands a considerable amount of most physicians’ time.
Just what physicians are running up against was emphasized in a recently published survey of a nationally representative sample of more than 1,500 parents. Fifty-four percent strongly agreed with the statement, “I am concerned about serious adverse effects of vaccines.” One-quarter of parents believed some vaccines cause autism, a figure that climbed to 37% among Hispanic parents. Particularly disturbing, in Dr. Anderson’s view, was the finding that 11.5% of parents had refused at least one physician-recommended vaccine (Pediatrics 2010;125:654-9).
