Four approaches to the disease now look most promising. The two doctors and their teams want to develop anti-viral drugs to treat infected patients, engineer antibody-based vaccines to ward off the disease, elucidate how the virus attacks the body, and discover what "cofactors"--or additional factors--cause some people infected with the virus to contract full-blown AIDS while others go unaffected...
...anti-viral drugs are on the cutting edge of Hirsch and Groopman's research. They are azidothymidine (AZT), a synthetic drug that was originally designed to combat cancer, and alpha interferon, a relatively new, genetically-engineered substance. Hirsch has just concluded a two-year placebo-controlled, double-blind study of 24 AIDS and ARC patients treated with the interferon, whose results will be revealed in June. In addition, both Hirsch and Groopman are participating in a nation-wide study of AZT in AIDS and ARC patients. Hirsch has already enrolled more than 100 patients, while Groopman is in the process...
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 participated in a field test of the vaccine last year by allowing 250 of his piglets to be inoculated. None of them or of others involved in the test contracted the disease, and in January the USDA licensed Biologics Corp., a vaccine manufacturer in Omaha, to put Omnivac...
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...
Bethesda Naval is the hospital of Presidents. Ronald Reagan went there last year to have a cancerous polyp removed from his colon. Richard Nixon was treated for viral pneumonia at the 500-bed facility in 1973. Lyndon Johnson had his gall bladder excised at the hospital in 1965 then proudly displayed his scar to anyone who cared to see it. Bethesda, in the northwest outskirts of Washington, D.C., is also a jewel in the crown of the U.S. military health care system, whose 688 facilities care for the nation's wounded in time of war. But presidential patronage notwithstanding...
