Barré-Sinoussi & Montagnier: Discovering the Cause of AIDS | Heroes of Progress | Ep. 10

Without Barre-Sinoussi and Montagnier’s contributions, humanity’s crusade against AIDS would not be as advanced or successful as it is today.

Rapid UTI Test Cuts Detection Time to 45 Minutes

“The Longitude prize was established in 2014 to incentivise a ‘cost-effective, accurate, rapid, and easy-to-use test for bacterial infections that will allow health professionals worldwide to administer the right antibiotics at the right time.’

The winning Sysmex Astrego’s PA-100 AST system is based on technology from Uppsala University in Sweden. A 400-microlitre sample of urine is placed on a phone-sized cartridge and then into a shoebox-sized analyser unit. It can spot bacterial infection within 15 minutes, and identify the antibiotic to treat it within 45 minutes.

Previously, doctors would send a sample to a laboratory for tests with results in 24 hours, giving a turnaround time of two or three days.”

Zimbabwe Turns Tide on HIV

“Zimbabwe’s adult population has come to embrace HIV treatment. The Zimbabwe Population-based HIV Impact Assessment Survey conducted in 2020 revealed 86.8% of adults living with HIV knew their status, and of those who were aware that they were living with HIV, 97% were receiving antiretroviral treatment.

About 1.4 million people in Zimbabwe are living with HIV, and the health ministry says that some 1.2 million Zimbabweans are on ARVs.

The huge uptake of ARVs has been the main reason for a 50% decline in the national HIV incidence over the past 10 years.”

HIV Vaccine Triggers Rare and Elusive Antibodies in Humans

“Vaccines typically work by eliciting a similar immune reaction to what’s seen during a real infection. But in the case of HIV, vaccine developers have to dramatically expedite the process, calling forth antibodies in weeks that would usually take years to show up. 

Now, in a study published Friday (May 17) in the journal Cell, scientists have demonstrated that this feat is possible in humans…

The trial included 20 HIV-negative volunteers. Fifteen received two vaccine doses, spaced two months apart, while the remaining five got a third dose four months after their second. Tests showed that two doses of vaccine triggered a robust response from immune cells and kicked off the production of broadly neutralizing antibodies. The team further confirmed the presence of these antibodies in the three-dose group by closely analyzing their immune cells.”

Wild Poliovirus Transmission Halted in Southern Africa

“Following thorough assessments in Malawi and Mozambique, an independent Polio Outbreak Response Assessment Team (OBRA) today recommended the closure of the wild poliovirus type 1 (WPV1) outbreak in Malawi and Mozambique, marking a significant milestone in the fight against polio in the African region.

The last WPV1 case in the African Region, linked to a strain circulating in Pakistan, was reported in Mozambique´s Tete Province in August 2022. A total of nine cases were detected in Mozambique and neighbouring Malawi, where the outbreak was declared in February 2022. In a coordinated response, more than 50 million children have been vaccinated to date against the virus in 5 countries in southern Africa.

The meticulous evaluation carried out by the OBRA team included two in-depth field reviews and supplementary data review, concluding that there is no evidence of ongoing wild polio transmission. The assessment considered the quality of the outbreak response, including the overall population immunity, supplementary immunization campaigns, routine immunization coverage, surveillance systems, vaccine management practices, and the level of community engagement.”
