Valneva and LimmaTech enter into a strategic partnership to accelerate the development of the world’s most clinically advanced tetravalent Shigella vaccine candidate
Valneva press release (8/1)
Last week, Valneva and LimmaTech Biologics AG announced a new strategic partnership and exclusive licensing agreement for the development, manufacturing, and commercialization of Shigella4V, a tetravalent bioconjugate vaccine candidate against shigellosis. Shigellosis is caused by Shigella bacteria and is the second leading cause of fatal diarrheal disease globally, particularly in low- and middle-income countries. There are currently no approved vaccines for Shigella. Under the agreement, LimmaTech will receive support for conducting Phase 2 clinical trials of the vaccine candidate in low- and middle-income countries, which are expected to begin later this year. Then, Valneva will be responsible for the further development of the vaccine candidate through potential regulatory approval and commercialization if approved.
Spanish lab sterilises mosquitoes as climate change fuels spread of dengue fever
Reuters (8/1)
The Biological Pest Control Centre in Valencia, Spain is releasing thousands of sterilized tiger mosquitoes, one of the species whose females transmit dengue to humans, to reduce the spread of dengue and other vector-borne diseases in Europe, as climate change has led to an expanding population of tiger mosquitoes across the continent and rising dengue rates globally. The lab employs an electron accelerator that uses radiation to sterilize the males, releasing an estimated 45,000 male mosquitos every week, who then unsuccessfully mate with the disease-spreading females, leading to an eventual reduction in the overall mosquito population. Similar sterilization techniques have been previously used to address disease vectors, but the Spanish lab is pioneering its use on the tiger mosquito.
WHO prequalifies Biological E novel oral polio vaccine
CIDRAP (7/30), features the Bill & Melinda Gates Foundation
Last week, Indian company Biological E announced that the World Health Organization (WHO) has prequalified its novel oral poliovirus type 2 vaccine, a next-generation live attenuated oral vaccine, which can hopefully help reduce the incidence of vaccine-derived poliovirus, along with Indonesia PT Bio Farma's vaccine that was prequalified earlier this year. Cases of vaccine-derived poliovirus have increased in recent years in areas with low immunization rates. The new vaccine has improved genetic stability and carries a lower chance of starting new outbreaks of vaccine-derived virus compared to currently available poliovirus type 2 vaccines. Biological E said its manufacturing facilities can produce more than 500 million doses each year, with Indian regulators already having cleared the vaccine for export purposes.
