Chickenpox vaccine might reduce shingles risk

December 4, 2009 US researchers looked at the health records of more than 172,000 children who were vaccinated with the varicella or chicken pox vaccine between 2002 and 2008. They found, over an average of 2 1/2 years after receiving the vaccine, only 122 cases of shingles occurred among the children-- an unexpectedly low rate.

The study is the largest of its kind and is published in the December issue of the Pediatric Infectious Disease Journal.
