AIDS Vaccine Research Starting Over

Posted: Updated:

BETHESDA, MD - There's been a major setback in the search for an HIV vaccine.

Researchers found two of the most promising test trials actually made patients more likely to become infected. Scientists aren't sure what went wrong.

Tuesday at a summit meeting the National Institutes of Health told scientists it's time scrap years of research and go back to basics.

"It's kind of getting the community together, pausing, putting everything on the table and re-looking at what the approach is," said Dr. Anthony Fauci, National Institute of Aids and Infectious Diseases.     

More experimental vaccines are in the works, but none of them are as developed as the human trials that failed.

Instead of rushing to find a vaccine, the National Institutes of Health want scientists to focus on basic questions that remain unanswered.
