Bavarian Nordic A/S plans to buy two travel vaccines plus a phase III chikungunya vaccine candidate from Emergent Biosolutions Inc. for about $380 million. Emergent will receive a $270 million up-front payment and perhaps as much as $110 million in future milestone payments. The vaccines are Vivotif, for preventing typhoid fever, and Vaxchora, for preventing cholera caused by Vibrio cholerae serogroup O1. Both oral vaccines have U.S. FDA and European approvals.

Any decision on whether to expand a five-year World Trade Organization (WTO) waiver of intellectual property rights for COVID-19 vaccines to diagnostics and therapies likely will be delayed longer than proponents had hoped. WTO members originally were scheduled to vote on expanding the waiver in December, but the deadline was extended indefinitely when key members, including the U.S., pushed for a delay.

Greenlight Biosciences Holdings PBC has received regulatory approval from the Rwanda Food and Drugs Authority (Rwanda FDA) to start a first-in-human phase I/II trial of its mRNA vaccine candidate against COVID-19, GLB-COV2-043, as a booster for previously vaccinated individuals.

Harmonization and simplification won the day as the U.S. FDA’s Vaccines and Related Biological Products Advisory Committee (VRBPAC) looked toward the future of COVID-19 vaccines in the U.S. Jan. 26. The committee voted unanimously, 21-0, to recommend using the same strain composition for all COVID-19 vaccines available in the U.S., whether they’re used for primary doses or boosters. Such standardization also would align the composition of Novavax Inc.’s protein-based vaccine with that of the mRNA vaccines produced by Moderna Inc. and Pfizer Inc.-Biontech SE.

As the SARS-CoV-2 virus that’s responsible for COVID-19 continues to evolve across the world, a global response, similar to what’s used with influenza, would be ideal in evaluating and recommending vaccine strain composition changes from year to year. But “the current diversity of vaccine manufacturers and complexities in global supply of COVID-19 vaccines would make a globally coordinated, simultaneous vaccine composition evaluation and recommendation quite challenging,” the U.S. FDA said in its briefing document for the Jan. 26 meeting of the Vaccine and Related Biological Products Advisory Committee. 

A year and a half gone, two HIV vaccine studies shut down. That’s the case with the Janssen Pharmaceutical Cos. of Johnson & Johnson as the phase III Mosaico study of its HIV vaccine regimen was not effective in preventing infection compared to placebo. Based on a data and safety monitoring board’s report saying the study was not expected to hit its primary endpoint, Janssen discontinued the clinical trial more than a year ahead of its estimated March 2024 completion date.
