SANTA FE, N.M.--(BUSINESS WIRE)--The laboratory of Dr. Shan Lu at the University of Massachusetts Medical School (UMMS) has provided CytoDyn, Inc. (Pink Sheets:CYDY) with updated DNA-based H1 and H3 serotype influenza vaccines for the 2007-2008 flu season. Updating of the DNA-based flu vaccines was completed in less than 1.5 months following a recommendation by the World Health Organization. It takes much longer to make an updated flu vaccine using the wild or natural virus, a technique that was developed in the nineteenth century and is still being used by the major vaccine providers.
