2. www.global-campaign.org What is a microbicide? A substance that can reduce the transmission of HIV and other STI pathogens when applied vaginally and, possibly, rectally. They do not yet exist… First generation: Gels and creams In the future: Sponges, vaginal rings Gels with barrier devices

3. www.global-campaign.org Why We Need Female Controlled Methods Biology –Women are 2-4 times more likely than men to get HIV from unprotected sex Economics –Women are often dependent on men for income –Selling sex is a way of life Social & cultural traditions –Male entitlement to sex, female innocence about sex –Gender based violence Current methods (abstinence, fidelity and condom use) often require male consent, knowledge, or cooperation

4. www.global-campaign.org Potential advantages Easy to use Allows intimacy and improves sex Contraceptive and non-contraceptive versions Reduces risk of other serious STIs Likely to be inexpensive and available over the counter Could be used without partner’s cooperation (or possibly even awareness)

6. www.global-campaign.org How would they benefit HIV+ people? Reduce risk of re-infection with other HIV strains Help protect both partners Reduce risk of other STIs, yeast and bladder infections Allow conception while protecting partner

7. www.global-campaign.org How effective will they be? First microbicides may be 40-60% protective Second generation may be 60-80% Should be promoted as a “back-up” to condoms, not as a replacement –Use a male or female condom every time you have sex; if you absolutely can’t use a condom, use a microbicide –Use a microbicide with your condom for added pleasure and protection

8. www.global-campaign.org Potential public health impact If a 60% effective product Offered to 73 lower income countries Is used by 20% people reached by health care During half of unprotected sex acts… = 2.5 million HIV infections could be averted in 3 years including women, men and children

9. www.global-campaign.org How close are we? Ability to prevent HIV transmission from men to women is being tested Five candidates in final stages First results expected late 2007/early 2008 Likely to be only partially effective (if at all) Proof of concept possible by time of next AIDS Conference Ability to prevent HIV transmission from women to men, and during anal sex will be a next step
