PAHO on Tuesday named Brazil’s Bio-Manguinhos and Argentina’s Sinergium Biotech as regional hubs for the development and production of mRNA-based vaccines in Latin America.
Reuters reported that the initiative—backed by Unitaid’s Medicines Patent Pool among others—seeks to “tap existing manufacturing capacities to help transfer vaccine technology developed by Moderna,” with an immediate emphasis on the Massachusetts-based company’s Covid-19 shot. WHO is also supporting a similar mRNA…

Science Translational Medicine published a study last week showing that higher doses of benznidazole on a modified regimen eliminated Chagas disease in three mouse models—findings that challenge PAHO’s and WHO’s standard of care for the disease.
In lieu of the standard twice-daily, two-month regimen, University of Georgia researchers gave the animals a weekly dose (up to five times higher than the comparable daily dose) for 30 weeks. The treatment cleared infection and eliminated…

Gavi made a preliminary deal with GSK and Sanofi, securing up to 200 million doses of their vaccine candidate for the COVAX Facility.A Pan American Health Organization (PAHO) study attributed a 75% reduction in chikungunya cases in sections of a Brazilian municipality to the introduction of Wolbachia-infected A. aegypti mosquitoes, PAHO announced last week, noting that the data are preliminary.
A PAHO team conducted the research in collaboration with the World Mosquito Program (WMP) and Fiocruz, comparing chikungunya incidence in parts of the city of Niterói where Wolbachia-carrying mosquitoes were released to…
Serum Institute of India (SII) announced at the end of December that WHO has prequalified its 10-valent pneumococcal conjugate vaccine (PCV).
A press release said the company aims to sell Pneumosil in low and middle-income countries for $2.00 per dose—one-third lower than competitors GSK and Pfizer currently offer to Gavi countries, and less than 20 percent of the multinationals’ price to PAHO countries.
SII said it has been able to lower manufacturing costs by including only the…
