About avac
About AVAC

  • Founded in 1995

  • Use education, policy analysis, advocacy and a network of global collaborations to accelerate the ethical development and global delivery of new HIV prevention options as part of a comprehensive response to the pandemic

  • We’re on a road to nowhere

  • If you don’t know where you’re going, any road will take you there

  • It is a long and winding road

Highlights from 2011 in hiv vaccines r d
Highlights from 2011 in HIV Vaccines R&D

In May 2011, the Pox-Protein Public Private Partnership or “P5” (formed by Sanofi Pasteur, Novartis, US NIH, Gates Foundation, the US MHRP and the HVTN) debuts, designed to move from the RV144 Thai prime-boost vaccine trial results to a potentially licensable product for Thailand and elsewhere.

In 2009, the RV144 Thai vaccine was the first ever to demonstrate a modest effect of 31.2% in preventing HIV infection. In September 2011, immune responses predictive of risk in RV144 trial identified.

In August 2011, the HVTN 505 Phase II trial of a DNA-Ad5 combination expands its scope to include an investigation of whether the experimental vaccine regimen prevents HIV infection.

More than two dozen phase I & II trials are ongoing in 20+ countries worldwide. Promising antibody and animal studies are continuing.

Follow-on studies from RV144 in South Africa and Thailand in devlelopmemt.

HVTN 205US, Peru

Phase II trial to assess safety of DNA and MVA vaccines and immune responses of participants to see if these vaccines are helpful in fighting HIV infection.

Expected 2013

Phase IIb trial to assess ifDNA prime/rAd5 boost vaccine regimensignificantly reduce viral load in individuals who become infected with HIV.

HVTN 078Switzerland

Phase I/II trial to assess the safety and immune response in the mucosa of the vector vaccines NYVAC-B and the rAd5.

TaMoVac1Tanzania, Mozambique


Phase I/II trial to assess the safety and immune response of DNA priming and MVA boosting and to develop further HIV vaccine trial capacity building in Tanzania.



No effective HIV vaccine is available today; however, more than two dozen phase I & II trials are ongoing in 20+ countries around the world, including follow-on studies from recent large-scale trials.

Phase I/II trial to assess the safety and immune response of an adenovirus-based HIV-1 vaccine regimen.

HVTN 084


Brazil, Peru, Switzerland, US

Phase I/II trial to assesses the safety and immune response of two Ad5 adenoviral vector vaccines.

Investing in hiv vaccine research development
Investing in HIV Vaccine Research & Development Trials

Annual investments in HIV vaccine R&D 2000 – 2010 (US$ millions)












* Commercial sector estimates not available for years 2000 to 2004. For years available commercial funding figures are estimates based upon a review of HIV vaccine programs at each company.

** Other includes all national public sector funding apart from funding from the US and Europe.

Bottom line
Bottom line Trials

  • There remains an urgent need for new HIV prevention options, including an AIDS vaccine

  • An AIDS vaccine is possible

  • Now is the most exciting and promising – and increasingly complex – time in AIDS vaccine research

  • Investments in AIDS vaccine R&D today is an investment in the future and in ending the epidemic

  • It’s not just about the “product”
