A new, first-of-its-kind trial will assess the safety and immunogenicity of Bavarian Nordic’s MVA-BN mpox vaccine in pregnant and breastfeeding women and infants under two years old, two populations at risk of severe complications from mpox but not currently eligible for vaccination. MVA-BN is the only vaccine for mpox prequalified by the World Health Organization and is currently approved for healthy adults and adolescents, but additional data from this trial could help expand access for additional key populations amid the ongoing mpox outbreak. The trial, which will start early next year, is jointly funded by the Coalition for Epidemic Preparedness Innovations (CEPI) and Global Health EDCTP3.
Researchers from the University of Glasgow have developed a new drug that could help combat the spread of treatment-resistant malaria, as the disease continues to kill more than 600,000 people every year and Plasmodium falciparum, a mosquito vector that spreads malaria, grows increasingly resistant to artemisinin, the frontline malaria treatment. The drug, adapted from a cancer treatment approach, works by permanently disabling a protein that P. falciparum uses to duplicate itself in humans. The researchers behind the drug think it could be more effective than current drugs at all stages of malaria infection, potentially with only one dose.
A research team from the University of California, Santa Barbara has found a way to potentially reduce the spread of mosquito-borne diseases by disrupting male mosquitoes’ ability to hear, which is essential for them to mate and breed. Male mosquitoes rely on the sound of female mosquitoes’ wingbeats in order to find and mate with them. By altering a genetic pathway that male mosquitoes use for hearing, the researchers were able to stop them mating entirely, preventing female mosquitoes, the ones that spread diseases to humans, from having babies and reducing overall mosquito populations. Specifically, the researchers studied Aedes aegypti mosquitoes, which spread diseases including dengue, yellow fever, and Zika.
