Last week Main and other farmers were perplexed when the U.S. Department of Agriculture, under attack by critics, halted the sale of Omnivac-PRV, a new genetically engineered viral vaccine that immunizes swine against pseudorabies and may be the first of a whole generation of better animal vaccines. Main had...
Overblown press stories and Rifkin's rhetoric about the two cases have raised the specter of re-engineered microbes escaping into the environment with dire consequences. But most scientists are convinced that neither the Biologics viral vaccine nor the A.G.S. bacteria pose any threat to man, beast or plant.
Like earlier vaccines against pseudorabies, Biologics' Omnivac consists of pseudorabies viruses altered to prevent them from causing disease but still capable of triggering production of the antibodies that make swine immune. While the viruses in other vaccines are rendered harmless by conventional methods, the Omnivac viruses are altered by recombinant...
Says Veterinarian Roger Saline, who supervised the test of Omnivac on Kevin Main's piglets: "I think they chose the wrong product to attack. The deletion work rendered the vaccine less virulent and less able to reproduce."
Yet even Rifkin's critics concede that some good can come from his tactics. Says Biologics Executive Mike Bartkoski, still smarting over the ban on his company's vaccine: "We've been trying to get name recognition. Now, suddenly, because of Jeremy Rifkin, everyone knows of Biologics."
