HIV Vaccine Research Fails Leaving Science Hopeless
Scientists have no hope that HIV may be found in nearest future.
From times when HIV appeared, best scientists have been working to find HIV vaccine, millions of dollars have been spent on these researches, but now there is no hope that these efforts will give a result.
Researchers have tried antibodies to prevent HIV, they also tried to improve body's immune system, but non of these methods work. Merck's vaccine was believed to be efficient in treatment, but last year is was recalled, because those taking the vaccine appeared to make their immune systems more vulnerable for virus. Merck's failure was a shocking news for scientists.
Professor David Baltimore, president of the American Association for the Advancement of Science is one of those scientists who don't want to give the battle up. He says: "This is a huge challenge because to control HIV immunologically the scientific community has to beat out nature, do something that nature, with its advantage of four billion years of evolution, has not been able to do. Our lack of success may be understandable but it is not acceptable."
The next steps forward are going to be "gene therapy, immunotherapy, stem cell therapy". These methods will be considered in HIV vaccine development one by one and even combined. Yet scientists don't see any chances for vaccine to be available within coming 10 years.
"It is such a sad topic. We've been trying to make an HIV vaccine since the day it was discovered," said Dr Baltimore. "We've been working on a vaccine since then and we are no closer to a vaccine now than we were then."
