  3. No magic bullet; need smart combinations

  6. History Lessons A vaccine [or condom, or microbicide or tablet] that sits on the shelf is useless. Albert Sabin

  7. And an Old Challenge 8% Harm reduction for injection drug users 9% Condom access 10-12% Adults with access to HIV testing in Africa 11% Behavior change programs for men who have sex with men 16% Behavior change programs for commercial sex workers 33% Prevention of mother-to-child transmission 0% 40% 60% 80% 100% 20% • Can we deliver on the promise? • Global access to existing prevention options Source: UNICEF/UNAIDS/WHO 2009

  12. No magic bullet; need smart combinations • It’s behaviour • Adherence, adherence, adherence • Embrace the niche • Strategize the sequence

  13. Pathway to Reversing the Epidemic Deliver today Male & Female Condoms Demonstrate today HIV incidence Medical Male Circumcision ARV Tx as Px Deliver soon ARV PrEP Develop for tomorrow ARV microbicide Partially effective vaccine highly effective vaccine Time

  14. No magic bullet; need smart combinations • It’s behaviour, stupid! • Adherence, adherence, adherence • Embrace the niche • Strategize the sequence • Testing, testing, testing

  15. No magic bullet; need smart combinations • It’s behaviour, stupid! • Adherence, adherence, adherence • Embrace the niche • Strategize the sequence • Testing, testing, testing • Watch our language

  16. An Evolving Lexicon • ART • ARV • Oral PrEP • PEP • Topical PrEP • Microbicides • Long-acting methods • TasP • TisP • T4P • TnT • TLC+

  17. No magic bullet; need smart combinations • It’s behaviour, stupid! • Adherence, adherence, adherence • Embrace the niche • Strategize the sequence • Testing, testing, testing • Watch our language • Four questions

  18. Four Questions • Who needs what? • Who wants what? • Who gets what? • Who pays?

  20. Money, Money, Money • “Science of Prioritization and the Primacy of Targeting” Ward Cates, personal communication, the day before yesterday • “Substantial changes are needed to achieve a more targeted and strategic approach to investment in the response to the HIV/AIDS epidemic that will yield long-term dividends.” Towards an improved investment approach for an effective response to HIV/AIDS, Schwartländer B et al, Lancet, 3 June 2011 • “If one accepts the tenet that science should inform policy, then the scientific data are speaking loud and clear. Global policy-makers must seriously consider these new data in their priority-setting and decision-making.” AIDS: Let Science Inform Policy, Fauci AS, Science, 1 July 2011

No magic bullet; need smart combinations • It’s behaviour, stupid! • Adherence, adherence, adherence • Embrace the niche • Strategize the sequence • Testing, testing, testing • Watch our language • Money, money, money • Four questions • Scientific data do not change the world—programmes and policies backed by civil society, donors, implementers and governments do
