Advocates for the Prevention of HIV in Africa (APHA) announces that its co-founder and Executive Director, Yvette Raphael, has been awarded the prestigious Mani L. Bhaumik Breakthrough of the Year Award for her pivotal role in advancing HIV prevention through the development and testing of Lenacapavir, the revolutionary long-lasting HIV prevention drug.
The award, established by the American Association for the Advancement of Science (AAAS), recognizes three key contributors to this medical breakthrough: Wesley Sundquist (University of Utah), who provided foundational scientific research; Moupali Das (Gilead Sciences), who championed clinical development; and Yvette Raphael, who ensured clinical trials were inclusive, ethical, and community-centered.
As Chair of the PURPOSE 1 Advisory Board, Raphael transformed clinical trial practices by insisting on the inclusion of young women, adolescents, and pregnant women in sub-Saharan Africa. This inclusive approach led to groundbreaking results: 100% efficacy in preventing HIV infections with just two injections per year.
Raphael's leadership exemplifies how community engagement improves scientific outcomes. While celebrating this significant breakthrough, APHA acknowledges that more research is required to find an HIV vaccine and remains committed to ensuring these innovations become accessible to all who need them.
The organization recognizes that Raphael's work has required support from her Board, colleagues, program partners, fellow advocates, researchers, and communities, demonstrating that when scientists, pharmaceutical companies, and community advocates collaborate with mutual respect, extraordinary progress becomes possible.
In 2023, malaria caused 597 000 deaths worldwide, according to the World Health Organization, with most occurring in Africa, where the deadliest malaria parasite, Plasmodium falciparum, is most prevalent. Once inside the body of an infected person, the parasite relies on a process called glycolysis—breaking down glucose (a sugar)—to produce energy and stay alive.
A new study at Stellenbosch University (SU) found that blocking the enzymes involved in this process could cut off the parasite’s primary energy source and kill it. Some of these enzymes could also be good targets for new malaria drugs.
A study by Wits University and Harvard confirms that South Africa’s 2013 sodium reduction legislation has successfully lowered blood pressure and improved public health.
Excessive sodium intake increases the risk of cardiovascular disease, which causes 20 million deaths globally each year. South Africa was the first African country to mandate sodium limits in processed foods. Researchers found a 10% drop in sodium intake over seven years, with more people achieving ideal consumption levels. Even small reductions in sodium correlated with lower blood pressure.
The law required sodium cuts in 13 food categories, including bread and processed meats, with reductions of up to 70% by 2016 and further cuts by 2019. Lead researcher Prof. Thomas Gaziano noted that even a slight blood pressure drop could prevent thousands of deaths annually.
Prof. Steve Tollman of Wits Agincourt Unit highlighted that mandatory regulations are more effective than voluntary measures. The study, involving 5,000 adults in rural South Africa, suggests other countries could adopt similar policies to save lives.
Researchers at the University of the Witwatersrand in Johannesburg, South Africa (Wits University) in collaboration with Huzhou University in China have discovered a way to protect quantum information from environmental disruptions, offering hope for more reliable future technologies.
A critically endangered new species of killifish sampled from an ancient forest in Kenya in 2017 and 2018 has been described in the journal Zootaxa. Nothobranchius sylvaticus, from the Latin meaning “pertaining to the forest”, is also the first known endemic killifish to persist in a forest.
