The challenges in primary care are many, and one of increasing importance is what to say to vaccine refusers. After much debate and thoughtful discussion, my medical partner, Dr. Janet Casey at Legacy Pediatrics, decided that the practice would refuse to care for the refusers.
Over the years, I have accepted such patients into my practice and worked with them to gain their confidence and debunk the many myths about the safety of vaccination that are so visible on the Internet. The approach worked well, and by the time the children were 1 year of age, I cannot remember but a handful of parents who did not come around to realize that it was best to vaccinate. However, with the recent measles outbreak at Disneyland in California, pertussis at epidemic proportions in pockets of the United States and elsewhere in the world, and the antivaccine voices gaining more and more attention, I agree, it is time to take a stand.
When a family brings their unvaccinated or undervaccinated child into the waiting room of a physician’s practice, that family is potentially exposing others in that waiting room to serious infectious diseases – that is not fair. In the waiting room may well be a patient who is on chemotherapy or immunotherapy or otherwise immunocompromised, and he relies on the “herd immunity” achieved by vaccinations of those who can safely be vaccinated for individual protection and public health. Those patients who have weakened immune systems did not choose to have their medical condition, whereas the vaccine refusers are choosing not to vaccinate their child (or typically themselves as well). And the reasons they are choosing not to vaccinate are based on misrepresentation of medical facts, fabrications of safety concerns, long ago disproven speculations by well-meaning and not so well-meaning physicians and scientists, pseudoscience published in pseudoscientific journals, and/or general distrust of the federal government that mandates vaccinations for the good of the public health.
My personal experience with vaccine scares dates back to a time when whole-cell pertussis vaccine was the only pertussis vaccine available. I was a medical student, resident, and then an infectious diseases fellow during the escalating debate about the significant side effects of vaccines. I joined in the chorus of voices questioning the need for clear data on the problem, and then the pursuit of a safer acellular pertussis vaccine. The physician community and the public were ready for change, and the National Institutes of Health took the lead in organizing multiple studies and clinical trials leading to eventual replacement of the whole cell pertussis vaccine with the current acellular vaccines.
Much more recently, at the request of National Institutes of Health, I led studies of the safety of thimerosal preservative in multidose vaccine vials that appeared in the Lancet (2002;360:1737-41); Pediatrics (2008;121:e208-14) and the Journal of Pediatrics (2009;155:495-9). Using the data from those three studies, the World Health Organization (WHO), the United Nations, the Institute of Medicine, and other organizations were able to see that the metabolism and elimination from the body of ethylmercury in thimerosal was dramatically faster, compared with methylmercury in fish. Therefore, the presumption of possible accumulation of mercury in the body of infants receiving vaccines from multidose vials when such vaccines were closely spaced was disproven by scientific data.
In plain language, there was never a known risk from thimerosal, but a premature, hurried decision was made to mandate removal of thimerosal from vaccines given to children in the United States and western Europe; thereby the myth lives on that thimerosal is not safe. Yet thimerosal is safe, and the WHO continues to advocate use of thimerosal in multidose vaccine vials. Nevertheless, I have been criticized personally on the Internet for this work. The accusation is that I, the rest of the scientists who participated in the study, and the NIH oversight were biased because our academic institutions had previously received funding from vaccine companies to perform clinical and translational research. I received many hate e-mails and even a death threat.
To close this column with a sense of humor, I suggest you Google the responses by U.S. presidential hopefuls on their stand with regard to vaccine refusers. The comments, then the reversal and “corrections” to their comments is amusing. The presidential hopefuls quickly recognized that the right to choose may not be the best policy for the public health of American citizens. Refusing to vaccinate a child potentially harms the child and may harm others!
