HIVR4P 2016: Huge Diversity in HIV Vaccine Research Discussed at Prevention Conference

The HIV vaccine research field is currently going through probably its most fertile and diverse period yet, and a high proportion of presentations at the HIV Research for Prevention conference (HIVR4P 2016) last week in Chicago were devoted to a multiplicity of different approaches towards designing vaccines to prevent HIV infection.


HIVR4P 2016: Rings, Films or Inserts? Prevention Products Need to Make Sense in Women's Lives

"We need to think outside of the box," Sharon Hillier of the Microbicide Trials Network told participants at the HIV Research for Prevention (HIVR4P 2016) conference this week in Chicago. Researchers should not be aiming to develop the most scientifically elegant solution for HIV prevention, but should "figure out how to make products that can really fit into people’s lives."


HIVR4P 2016: Vaginal and Rectal Bacteria May Influence HIV Transmission and Microbicide Efficacy

A number of presentations at the HIV Research for Prevention Conference (HIVR4P 2016) this week in Chicago looked at the influence of vaginal bacteria on HIV susceptibility, with one study finding that vaginal bacteria may have profound effects on levels of certain drugs used as microbicides -- but not others. A poster at the conference also looked at bacteria in the rectum in gay men, finding a correlation between condomless anal sex and changes in the predominant bacterial species which may similarly increase susceptibility to HIV infection.


HIVR4P 2016: New Microbicide Enema Achieves High Levels of Drug in Rectal Tissues in Monkeys

Rectal microbicides that protect against HIV transmission via anal sex are a bigger technical challenge than vaginal ones. The rectal lining is more delicate than the vaginal lining, so safety has been an issue; research has shown that many of the gel formulations used in lubricants damage rectal cells and may actually enhance HIV transmission.


HIVR4P 2016: Policymakers' Inaction is Leading People to Take "PrEP in the Wild"

An increasing number of gay men and others at risk for HIV are seeking to protect their health with pre-exposure prophylaxis (PrEP), but the lack of PrEP provision and regulatory approval in many countries is leading people to take it without medical supervision and on an ad-hoc basis. This will undermine the safety and effectiveness of PrEP, said Jerome Galea as he presented results of the PrEP in the Wild survey at the HIV Research for Prevention conference (HIVR4P 2016) this week in Chicago.

HIVR4P 2016: More Viral Suppression Needed to Reduce HIV Infections Among Gay Men

HIV suppression on antiretroviral therapy (ART) would need to increase substantially among men who have sex with men in order to take advantage of "treatment as prevention" to reduce the rate of new HIV infections, according to a mathematical modeling study presented at the HIV Research for Prevention conference (HIVR4P 2016) taking place this week in Chicago.
