L’ORÉAL-UNESCO FOR WOMEN IN SCIENCE 2016 INTERNATIONAL AWARDS WOMEN IN SCIENCE have the power to change the world The L’Oréal-UNESCO For Women in Science programme was founded in 1998 with a simple aim; to ensure that women are fairly represented at all levels in science. We face unprecedented challenges in our world; climate change, sustainable energy, affordable healthcare, security among other issues. Part of the solutions will come from science and science needs women. Those recognized by the L’Oréal-UNESCO programme have already proved how transformative their science can be in addressing these challenges. Science is indeed part of the future, and it needs every talented mind available, be they men or women. The L’Oréal-UNESCO For Women in Science programme aims to ensure that research in every field takes full advantage of the intelligence, creativity and passion of one-half of the population of the planet. The world needs science, science needs women because women in science have the power to change the world. Isabel Marey Semper General Manager L’Oréal Foundation WOMEN IN SCIENCE have the power to change the world Gender equality is a global priority for UNESCO. In general, the situation for women and girls in terms of access to education, especially higher education, career progression and participation in decision making processes, remains a matter of concern. As ‘UNESCO Science Report: towards 2030’ shows, the disparity is particularly evident in the natural sciences where the number of women participating in science still lags behind in many areas like the physical sciences and engineering. -

The FACTS 001 trial involving 2059 South African women showed no overall HIV prevention benefit of the gel. However, a sub-group analysis based on gel use confirmed by tenofovir detection in genital fluid, showed a 52% reduction in HIV infection. The CAPRISA study had reported in 2010 that tenofovir, applied as a gel before and after sex, reduced HIV infection by 39% overall and by 54% in women who used the gel consistently. CAPRISA is an official research institute of the The results of the FACTS 001 study, which was led by Professors Helen Rees and University of KwaZulu- Natal and Columbia Glenda Gray, were markedly influenced by the large proportion of women who did University. not apply the gel consistently.

What Can We Learn from the HIV Response About Pandemic Preparedness for SARS-Cov-2 and Beyond
What can we learn from the HIV response about pandemic preparedness for SARS-CoV-2 and beyond CLASS SESSIONS Dates: June 7 and 8, 2021 Time : 8:30am to 12:30pm Location: TBD/Zoom INSTRUCTORS Salim S Abdool Karim [email protected] / [email protected] Quarraisha Abdool Karim qa4@cumc. columbia.edu / [email protected] Course Description The SARS-CoV-2 pandemic is the most recent and challenging pandemic facing humanity in the 21st century. Country responses to this 2020 pandemic provide important insights on retuns on public health investments made in response to the HIV pandemic but also shaped by political leadership and the balance or prioritisation of saving lives, livelihoods and viral suppression. The role of science and knowledge generation has been unprecedented including the development of several efficacious vaccines. The emergence of new variants of concern of SARS-CoV-2 even as SARS-CoV-2 vaccines are being rolled out across the globe; continued high rates of infections and deaths underscore our inter-dependence and the many research questions that remain unanswered. Global responses to the HIV pandemic have important lessons for responses to SARS-CoV-2. This interactive course will share lessons learnt from responses to SARS-CoV-2 including its interaction with HIV and what lessons our HIV response has for responding to SARS-CoV-2. Course Objectives By the end of the course, students will have a greater appreciation of key elements of an effective response to SARS-CoV-2; the interaction between SARS-CoV-2 and HIV; and lessons from HIV for SARS-CoV-2. -

CONTACT: Lisa Rossi +1- 412- 916-3315 (mobile) [email protected] FOR IMMEDIATE RELEASE Results of CAPRISA 004 a turning point for HIV prevention, say MTN researchers conducting VOICE Tenofovir gel used before and after sex reduced HIV by 39 percent, raises bar for VOICE Study testing daily gel use and ARVs for preventing HIV in women VIENNA, July 19 – Researchers who conducted a study testing a vaginal microbicide with an antiretroviral (ARV) drug called tenofovir found its use before and after sex was significantly more protective against HIV infection than a placebo gel among women at high risk of HIV. Results of the study, known as CAPRISA 004, are to be reported at the International AIDS Conference (AIDS 2010) in Vienna and published online by the journal Science. CAPRISA 004 involved 889 women from Durban and a nearby rural community in South Africa, where women are at especially high risk of acquiring HIV through sexual intercourse. Women were randomly assigned to one of two study groups – tenofovir gel or placebo gel with no active ingredient –and instructed to use the study product in a regimen timed before and after sex. At the end of the study, there were 39 percent fewer HIV infections among women who used tenofovir gel before and after sex than among those who used the placebo gel. The study was conducted by the Centre for the AIDS Programme of Research in South Africa (CAPRISA). “This study has established proof of concept that a vaginal microbicide containing an ARV can protect women from HIV. This is an incredibly important achievement for which the CAPRISA team is to be congratulated. -

These results were historic. After nearly two decades of research,s thi was the first clinical trial to show that a vaginal microbicide could provide a safe and effective way to prevent sexual transmission of HIV. The gel also provided a 51% protective effect against herpes simplex virus type 2 infection (HSV‐2). The announcement raised questions about the most appropriate next steps: making the gel available to women at risk based on this single trial; planning and implementing additional trials to confirm the results; or waiting for the results of the VOICE (Vaginal and Oral Interventions to Control the Epidemic) trial, another trial of 1% tenofovir gel using a different dosing strategy. To identify priority next steps, WHO and UNAIDS convened a meeting on 25‐26 August 2010 that drew together more than 80 diverse stakeholders from a range of countries.
