New Inoculation for Smallpox Is Promising
From Times Staff and Wire Reports
An experimental smallpox inoculation using a weakened form of the vaccinia virus may protect people from biological attacks and could also be used on those with damaged immune systems, researchers said Wednesday.
The experimental vaccine protected monkeys against a virus related to smallpox without causing some of the dangerous side effects of the older vaccine, the U.S. researchers reported in the journals Nature and the Proceedings of the National Academy of Sciences.
