Dow Agro process gets green light - Indianapolis Star

A matter of speed Randy Woodson, dean of Purdue University's College of Agriculture, said the Technology could become critical as viruses mutate and require ever-changing vaccines to fight them. Vaccines can be Made from plants faster than from animals, he noted."It's just a matter of time before this will be the strategy for producing vaccines for human diseases," Woodson said.Plant-cell vaccines avoid the contamination that can occur with traditional versions Made, for example, by inserting a virus in chicken eggs, then harvesting the fluid, killing the virus and using the resulting mix in the injection.Producing the vaccines in a fermenter also sidesteps potential for contamination inherent in research under way at other companies wanting to grow pharmaceuticals in plants. Pollen from nearby plants can pollute pure strains even in greenhouses.Dow Chemical's pharmaceutical unit in Michigan would undertake any attempts to shift the Technology to human vaccines, Mercer said. That likely would be several years in the future if it happens.Mercer said the vaccines might be manufactured in Indiana or elsewhere.By 2009, Dow AgroSciences hopes to have vaccines for equine West Nile virus and avian flu, with other vaccines likely to follow.Dow AgroSciences thinks it can turn vaccines into a $500 - More available
