Researchers from Inovio Pharmaceuticals Inc. described the protective effect exerted by INO-4500, a DNA vaccine produced using the Syncon technology, against lethal Lassa virus in nonhuman primates.

Orthogon Therapeutics LLC has closed an oversubscribed financing round, with funding to be used to accelerate the development of its first-in-class treatments for managing BK virus reactivation in transplant patients.

Sunshine Biopharma Inc. announced it has developed an orally active protease inhibitor that showed dose-dependent antiviral activity in mice infected with SARS-CoV-2.

Chinese researchers presented a novel recombinant oncolytic HSV-1, named SONC-103.

Although it does not generally infect humans, a single mutation of the H5N1 virus in the highly pathogenic avian and bovine clade 2.3.4.4b could overcome this barrier and possibly trigger a pandemic. Scientists at The Scripps Research Institute have warned of this possibility after studying the three-dimensional structure of the viral hemagglutinin and seeing how a change in one amino acid would make it more suitable for the human cell receptor. The researchers stress the need to monitor new mutations of this virus in order to act quickly in case the global jump to our species occurs.

Researchers from the Fourth Military Medical University (Air Force Medical University) have identified novel antimicrobial molecules.
