概要

 In a Tanzanian village, residents report a dramatic drop in malaria cases thanks to the R21 vaccine trial, with The Independent noting that booster doses have further reduced infections over five years, even benefiting adults by blocking parasite transmission in mosquitoes. Dr Angela Gwakisa, overseeing the Bagamoyo district study from Oxford University's Jenner Institute, confirms the trend, while mothers like Amina praise its protection for children in high-risk areas.

Yet challenges persist amid funding shortfalls. CIDRAP News warns that slashed US aid via USAID has sparked malaria comebacks in burdened nations, leaving gaps as governments negotiate support. Meanwhile, Burkina Faso celebrates two years of R21 rollout, with Gavi reporting a 32% plunge in national cases from 10.8 million in 2024 to 7.3 million in 2025, and deaths falling 44% from 3,523 to 1,979. Among under-fives, cases dropped 39% and mortality over 40%, crediting four-dose schedules at 5, 6, 7, and 15 months alongside partners like UNICEF, WHO, Jhpiego, and USAID.

Misinformation threatens progress. TDR details a recent infodemic in Togo, where social media influencers spread rumors days before R21 introduction, prompting the Optimising Malaria Vaccine consortium—including TDR—to share trust-building strategies as RTS,S and R21 expand across Africa. Health Minister Robert Kargougou hailed the vaccines' role in curbing severe cases nationwide.

These developments underscore vaccines' potential to avert up to 600,000 annual deaths, per The Independent, though experts urge sustained funding and anti-misinformation efforts to sustain gains.
