Cansino Biologics Inc. has entered a development and commercial supply partnership with Aerogen Ltd. for an inhalable version of its COVID-19 vaccine, Convidecia, also known as Ad5-nCoV. Cansino will combine Convidecia with Aerogen’s vibrating mesh aerosol drug delivery technology to produce a consistent droplet size for optimal lung deposition.
Rnaimmune Inc., which in April raised a $10 million seed round to support its discovery and development of RNAi therapies, said it is now studying the neutralizing effects of its mRNA-based COVID-19 vaccine candidate on the Omicron variant.
Abogen Biosciences Co. Ltd. has raised $300 million in a series C+ round to support the development of its mRNA products, specifically to support the development of its COVID-19 mRNA vaccine and expand to the global market.
In addition to the four COVID-19 vaccines it has provisionally approved, Australia’s Therapeutic Goods Administration (TGA) is recommending that two more vaccines – Sinovac Biotech Ltd.’s Coronavac and Astrazeneca plc-Serum Institute of India’s Covishield – be considered “recognized vaccines.”
More than 21 months since the SARS-CoV-2 virus was first identified in Wuhan, China, the questions just keep coming, and the longer they go unanswered, the more divisive the opinions become. Controversies over the efficacy of current vaccines, over whether boosters are necessary for the general population, over the safety of COVID-19 vaccines for young children, over how to distribute the shrinking supply of highly effective monoclonal antibodies, and over how the virus originated in the first place – all of these looming questions have created a firestorm of uncertainty that will not stop burning.
When the SARS-CoV-2 virus first emerged in the U.S., the knee-jerk reaction by biopharma researchers was to make the best vaccines and therapeutics possible and to do so quickly. Since then, the number of those that have entered development has reached 1,001, more than for any other viral infection aside from HIV.
In a couple of deals worth more than $500 million, Everest Medicines Ltd. is picking up Asian rights to Providence Therapeutics Holdings Inc.’s mRNA candidates, including rights to a mRNA COVID-19 vaccine candidate currently in phase II testing.
PERTH, Australia – Engeneic Ltd. has begun a phase I trial of its nanocellular COVID-19 vaccine, which in preclinical animal studies stimulated a broad antiviral response against mutant strains of the virus, including the virulent Delta strain sweeping across Australia.
Chinese companies are finding that their COVID-19 vaccines are effective as booster shots and against variants of the virus, as data from more studies emerge. Those who have received the third dose of Sinovac Biotech Ltd.’s COVID-19 vaccine, Coronavac, showed 2.5-fold higher neutralizing potency against the Delta variant, compared to COVID-19 convalescents and two-dose vaccinees.
LONDON – Conflicting data from around the world on the extent to which the Delta variant of SARS-CoV-2 is reducing the effectiveness of vaccines is generating uncertainty over the need, or not, for booster programs.
