The FDA has cleared HDT Bio Corp.’s IND application for HDT-321, a first-in-class prophylactic designed to protect against Crimean-Congo hemorrhagic fever (CCHF).
The envelope (E) proteins of Zika virus (ZIKV) and dengue virus (DENV) present a high degree of homology, which can lead to cross-reactive antibodies that exacerbate disease through antibody-dependent enhancement. This enormously challenges the development of effective ZIKV vaccines.
Effective vaccines against Staphylococcus aureus remain out of reach: 10 candidates that showed promise in preclinical animal models have failed in clinical trials. Researchers at Third Military Medical University and collaborators reasoned that one of the reasons might be that 70%-80% of the population has developed antibodies to the pathogen.
Immunoprecise Antibodies Ltd. is advancing its universal dengue vaccine program. Following the discovery and validation of a uniquely conserved dengue epitope using its Lensai platform, the company is now advancing to preclinical manufacturing for in vivo testing and virus neutralization analysis.
Combating Antibiotic-Resistant Bacteria Biopharmaceutical Accelerator (CARB-X) has awarded Baxiva AG $3 million to develop its multivalent glycoconjugate vaccine.
Researchers from the California Institute of Technology and collaborating institutions have developed a novel HIV vaccine candidate, a new germline-targeting Env SOSIP trimer called 3nv.2, that is designed to elicit antibodies targeting three key epitopes on the HIV envelope protein.
Francisella tularensis, the causative agent of tularemia, is capable of causing severe illness at extremely low infectious doses through inhalation. No licensed tularemia vaccines exist in most Western countries, and current candidates lack efficacy against pneumonic forms. This highlights an urgent need for more effective vaccine strategies.
The Nipah virus (NiV) from the Henipavirus genus is a bat-borne zoonotic pathogen that causes encephalitis and acute respiratory distress syndrome in humans. NiV infections have a very high fatality rate. No approved vaccine or therapeutics against NiV infection exist for use in humans despite its dangerous potential for causing larger epidemics.
The threat of another influenza pandemic arising from bird-to-human and then human-to-human transmission drives continuing efforts to develop effective vaccines against avian influenza. In the latest advance in this area, researchers at Novavax Inc. have reported a new vaccine against avian influenza strain A(H5N1) clade 2.3.4.4b.
