NEJM on measles in the U.S.

This week's issue of the New England Journal of Medicine includes two pieces that explore the status of measles in the U.S., particularly in relation to a 2005 outbreak in Indiana. That outbreak -- the largest in a decade -- was triggered by the return of a 17-year old unvaccinated girl who traveled to an orphanage in Romania as part of a church group.

One paper is a report tracing the spread of the virus from that individual through everyone she exposed. Titled "Implications of a 2005 Measles Outbreak in Indiana for Sustained Elimination of Measles in the United States" (available free), it concludes, in part:

"Measles was eliminated in the United States through high rates of routine childhood vaccination coverage. The outbreak in Indiana shows that states, localities, and health care organizations need to implement more effective policies to protect persons traveling abroad, home-schooled children, and health care workers against measles and other vaccine-preventable diseases. In addition, to preclude the experience of those countries where vaccine-preventable diseases have become epidemic through the refusal of vaccination, better communication strategies are needed concerning the adverse events associated with vaccines."

The second is a perspective essay by E. Kim Mulholland, M.D., from the London School of Hygiene and Tropical Medicine. Titled "Measles in the United States, 2006," Dr. Mulholland's conclusion is sure to raise the ire of critics of vaccine policy and safety. Putting the blame for outbreaks such as that in Indiana on those alleging vaccine safety issues, Mulholland writes:

"And as long as some groups within a given community respond to spurious claims about the risks of the vaccine by refusing to vaccinate their infants, further outbreaks will occur even in industrialized countries."
