Chanock, MD.Many of an estimated 10,000 "pneumonia-like" deaths in infants and young children annually may be traced to RS virus. This has made development of a vaccine against the disease a major goal of several National Institutes of Health investigators since the virus was isolated 12 years ago.Several aspects of this unusually virulent disease—which causes severe lung damage in children under two but little if any illness in older persons—are falling into place, Dr. Chanock believes.
