Sharp Debate Over HIV Vaccine Failure

Scientists Can't Agree on Future of HIV Research

HIV Vaccines: What Comes Next?

But earlier this week several HIV research advocacy groups called for the U.S. government to abandon efforts to develop an HIV vaccine. Homayoon Khanlou, MD, U.S. chief of medicine for the AIDS Healthcare Foundation, said that the money should instead be spent on increased HIV testing and treatment, which both help cut the risk of HIV transmission.

All the clinical trials that have been done with the vaccine have yielded no results," Khanlou told reporters. "They've left us with no clue in terms of which way to go."

Few researchers seemed willing to consider abandoning vaccine efforts entirely. But several described their field as being a crossroads.

"The idea that we shut everything we have done and get to do something else is absolutely insane," Mahmoud said.

He showed the audience of scientists a slide quoting Winston Churchill's famous speech to a group of British students during World War II. "Never give in. Never give in. Never, never, never, never," it read.
