Researchers at the University of Rochester Medical Center are testing a new oral vaccine to prevent infection with HIV, the virus that causes AIDS. The vaccine is unique because it is given as a pill, unlike most HIV vaccines tested to date that have been given as shots.

A clinical trial has launched in South Africa to study an investigational HIV vaccine regimen for safety and the immune responses it generates in volunteers. This experimental regimen is based on the one tested in the RV144 trial - -the first to demonstrate that a vaccine can protect people from HIV infection -- but is designed to potentially provide greater protection and is adapted to the predominant HIV subtype in southern Africa.

For more than three decades, scientists have tried unsuccessfully to develop an effective vaccine for HIV, the virus that causes AIDS. But now researchers say they have created an experimental drug that may function as a sort of "alternative" vaccine for the virus. The experimental drug, a protein known as eCD4-IG, blocks infection by keeping the virus from binding to the immune cells that are the virus's target. In tests on monkeys, the drug "candidate" proved to be extremely effective at blocking infection--even with the most virulent strains of HIV and its simian counterpart, SIV.

Researchers Carefully Tailor a Study to Find Patients to Test Going Off Antiretroviral Medication

A few days ago while in Abuja, I was surprised to hear the news presenter announce that a Federal High Court had “lifted the ban” on Dr Abalaka’s “vaccine” against HIV. I was struck by a number of things – an abiding discomfort at the quality of reporting on science and health matters in the Nigerian media; a sense of guilt that, in failing to tell our stories, younger Nigerians are at risk of repeating missteps of the past; and a fear that many, misled by the news item, may put their lives at risk.

Bill Gates said he expects a pair of advances by 2030 that will eliminate most of the damage from AIDS. Improved treatment and the development of a vaccine to prevent new infections are the “two miracles” needed to help turn the tide, the billionaire said Friday at the World Economic Forum in Davos, Switzerland.

In a study published in the journal Immunity, the researchers report that an investigational vaccine that elicited an immune response in an estimated 31 percent of participants was able to do so because of a particular antibody gene motif that is shared with rhesus macaques and other primates. "It turns out that this antibody response that can recognize this part of the HIV envelope is encoded in the genes present throughout primate development," said lead author Kevin Wiehe, Ph.D. "We found it in almost every primate species we studied." The drawback, however, is that this ancient response might compete with the response aimed at by experimental HIV vaccines - novel, broadly neutralising antibodies that can defuse the virus regardless of how it mutates.

Vaccines designed to protect against HIV can backfire and lead to increased rates of infection. This unfortunate effect has been seen in more than one vaccine clinical trial. Scientists at Yerkes National Primate Research Center, Emory University, have newly published results that support a straightforward explanation for the backfire effect: vaccination may increase the number of immune cells that serve as viral targets.

Dr. Deborah Anderson from Boston University School of Medicine and her colleagues are challenging dogma about the transmission of HIV. Most research has focused on infection by free viral particles, while this group proposes that HIV is also transmitted by infected cells. While inside cells, HIV is protected from antibodies and other antiviral factors. Anderson chides fellow researchers for not using cell-associated HIV in their transmission models: "The failure of several recent vaccine and microbicide clinical trials to prevent HIV transmission may be due in part to this oversight." . The Journal of Infectious Diseases (JID) has devoted their December supplement to this important and understudied topic.

The Journal of Virus Eradication is a new open-access online and print journal dedicated to the rapidly developing field of virus eradication. It is particularly interested in publishing original research on HIV, hepatitis viruses, HPV, herpes and flu but work on other viruses is also included. The first issue was successfully launched at the HIV and Hepatitis Five Nations Conference in London
on 8 December 2014 and is available now on the Journal website: www.viruseradication.com
