Survey looks at practice of dismissing families for refusing vaccines | AAP News | AAP Gateway [cached]

Dr. O'Leary
Dr. O'Leary The results are reported in "Characteristics of Physicians Who Dismiss Families for Refusing Vaccines" (O'Leary ST, et al. Pediatrics. Nov. 2, 2015, "The study raises interesting questions in terms of what is the impact for all involved when you have a policy like this," said lead author Sean T. O'Leary, M.D., M.P.H., FAAP, associate professor, Department of Pediatrics and Children's Hospital Colorado, University of Colorado. "Do those children end up getting vaccinated or not? If they don't end up getting vaccinated, you really haven't accomplished much." However, Dr. O'Leary said the practice of dismissing families who don't vaccinate "does send a strong message to families about how strongly you feel about the importance of vaccination."

We asked Dr. Mark Schleiss, director of Pediatric Infectious Diseases and Immunology at the University of Minnesota Medical School, and Sean O'Leary, an assistant professor of pediatrics at the University of Colorado, for the low-down on what makes up the MMR shot (including ingredients used to produce the vaccine that may be present in trace amounts).
If you've ever put a salve of Neosporin on a scraped knee, you've probably used about 140 times the amount of neomycin that's in the MMR, O'Leary calculated. Some parents, O'Leary said, express concerns that certain ingredients may be OK to eat but not injected. O'Leary says he often discusses vaccine ingredient concerns with families. "It's human nature to be afraid of what you don't understand," he said, "but all of these ingredients are well studied, and people who do understand them have no concerns about them."

Doctors in the South and Northeast were more likely to take this hardline stance, said study lead author Dr. Sean O'Leary, a pediatric infectious disease specialist at Children's Hospital Colorado in Denver.
But O'Leary said he's heard anecdotally that pediatricians across the nation have come under pressure to refuse to take on unvaccinated children, following the Disneyland measles outbreak that occurred earlier this year. "I'm hearing the practice has become more common, particularly in California, following the outbreak," O'Leary said. "Parents say, 'I don't want to take my child to a clinic with non-vaccinators and expose them to risk,' so there is parental pressure on some pediatricians." An ongoing medical debate continues to simmer over a doctor's right to refuse treatment for children whose parents are against vaccination, O'Leary added. There are a number of reasons why pediatricians take this tack, said O'Leary and Dr. H. Dele Davies, a member of the American Academy of Pediatrics' committee on infectious diseases. Pediatricians may also feel that they won't be able to establish a relationship with parents if they can't see eye-to-eye on vaccination, O'Leary said. "The pediatrician might feel that the physician/patient relationship may not be a productive one if they're so far apart in terms of a core concept like vaccination," O'Leary said. "Pediatricians consider vaccination one of the most important things they do." Finally, pediatricians sometimes use the threat of dropping a family to convince parents to agree to vaccination, O'Leary said. "It really convinces a lot of parents to go ahead and get their child vaccinated, because it's such a strong message about the importance of vaccination," he said. No one knows what happens to families who are dropped for vaccination refusal, which demonstrates the need for further research on this topic, O'Leary said. "This practice is pretty common, and we don't know what happens to those families," he said.
