Latest News on HIV Vaccine: Failure to Develop A Vaccine Still Yields Important Insights

6Medical experts and scientists are in the lookout for ways to control the spread of the HIV (Human Immunodeficiency Virus) infection. Aside from various information awareness campaigns, treatment, therapies, and other programs that are being implemented, scientists are also trying to create an HIV vaccine.

For many decades now, researchers are embarking on the quest to invent an HIV vaccine that will prevent the transmission of the virus. However, despite the persistence of scientists, the virus that causes AIDS proves to be very stubborn as well. Based on the latest news on HIV vaccine, efforts haven’t yielded any successful results. However, researchers note that the most recent failures still produced important insights. Such insights can be very useful in the next attempt.

Details of the study

The latest news on HIV vaccine reports that the HIV Research Section of the San Francisco Department of Public Health (SFDPH) and the U.S. Military HIV Research Program conducted a study on 3,000 HIV-negative people from various parts of North America, South America, the Caribbean and Australia.

During the course of the research, they were divided in groups. One group received doses of the experimental HIV vaccine while the others received placebo. The HIV vaccine was referred to as the “Merck vaccine”, primarily because such was developed by Merck & Co.

Results of the experiment

According to the researchers, 4.6 % of those who received the Merck vaccine still became infected with HIV. As for those who received placebo, there was a 3.1 % rate of HIV infection. Although the researchers cannot conclude on the statistical significance of the difference between the rates, they claimed that uncircumcised men had increased rates of becoming HIV infected as compared to men who were already circumcised.

Based on the latest news HIV vaccine, the infection rates were also higher among the subjects which were immune to the cold virus. Such conclusions were vital because scientists used the cold virus as one of their basis in ensuring that the HIV vaccine will penetrate the cells of the body.

Implications of the study

According to Dr. Merlin L. Robb from the U.S. Military HIV Research Program, the failure on the recent research “profoundly affected the HIV-vaccine development field.”

Among the most important information that the researchers were able to derive from the study was that they had to understand the role of the foreskin in increased HIV risks among uncircumcised men.

Through the latest news HIV vaccine, they also realized that researchers should also determine if there is any relationship between the immunity to the cold virus and the susceptibility to HIV infection.

Dr. Susan P. Buchbinder, director of the HIV Research Section at the SFDPH, notes that the study provided new insights that are vital for the development of a successful HIV vaccine. She further notes that it would have been impossible for the researchers to anticipate these concerns if the Merck vaccine did not fail. GP
