Vaccinating School Kids Can Protect the Whole "Herd" of Community Members

The findings come at a time when vaccine phobia is one of our largest public health concerns, with many parents worrying that immunizing kids can lead to adverse side affects. A recent survey revealed that one in four U.S. parents think that vaccines might cause autism, probably due in part to a 1998 paper published in the journal The Lancet that wrongly linked autism to vaccines–that paper has since been refuted, and fully retracted by the journal.

Now, scientists have more evidence that vaccines provide a public health benefit. Researchers studying youngsters in 49 remote Hutterite farming colonies in Canada found that giving flu shots to almost 80 percent of a community’s children created a herd immunity that helped protect unvaccinated older people from illness. As children often transfer viruses to each other first and then pass them along to grown-ups, the study provided solid proof that the best way to contain epidemics like the recent H1N1 outbreak is to first vaccinate all the kids. By immunizing the most germ-friendly part of the herd first, you indirectly protect the rest of the community, scientists say.
