For Tony Fauci, HIV/AIDS research was heartbreakingly frustrating because
time was on no one’s side. People died while he and other scientists
painstakingly went about their work conducting experiments and proving
themselves wrong. While researchers were testing and observing, AIDS activists
were criticizing and protesting, bearing grim signs reading SILENCE = DEATH.
Too little funding, they complained, and too little urgency. Fear and grief and
frustration hit hard.
Finally, President George H. W. Bush, who spoke about a “kinder, gentler”
America, boosted funding. Fauci put research in high gear. Still, it took three
years of intense research before Robert Gallo of NIH and Luc Montagnier from
the Pasteur Institute announced that they had identified the virus that causes
AIDS—a retrovirus that could incubate in the body for years before erupting into
full-blown AIDS.
Once the virus was isolated, researchers went to work to defeat it. Molecular
virologists started sequencing it. They examined the genetic code. Then
researchers discovered the antibody test, which allowed for prompt diagnosis.
They started experimenting with off-the-shelf compounds to see which might
inhibit the virus. But it was by no means a straight line. There were false hopes,
setbacks, and flat-out failures.
A promising drug, AZT, emerged from this work, and the medical
community felt a sudden, uncharacteristic burst of hope that the disease might be
reined in. But clinical trials and experience established that AZT lost
effectiveness over time because the virus developed resistance to it. Researchers
discovered the virus could replicate and mutate, getting around AZT. A setback,
which led to a question.
