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.
Now there are three. Moderna Inc. has posted strong phase III study data on its mRNA respiratory syncytial virus (RSV) vaccine, keeping pace with Pfizer Inc. and GSK plc’s candidates, which have May PDUFA dates. Moderna’s top-line results of the ConquerRSV pivotal efficacy study of mRNA-1345 show the vaccine hit its primary efficacy endpoints of 83.7% against RSV-associated lower respiratory tract disease in older adults.
Researchers from Guangzhou University of Chinese Medicine have presented preclinical results on a three-component vaccine, MPLA-Tn-KRN7000, as a tumor immunotherapeutic.
Researchers from Therapyx Inc. and Intravacc BV assessed the potential of intranasal administration of a novel gonococcal vaccine candidate consisting of outer membrane vesicles (OMVs) and microsphere (ms)-encapsulated interleukin-12 (IL-12 ms). It was previously demonstrated that female mice can be immunized intravaginally with gonococcal OMVs plus IL-12 ms to induce anti-gonococcal antibodies and resistance to genital tract challenge with live Neisseria gonorrhoeae.
Sen. Bernie Sanders (I-Vt.), the incoming chair of the U.S. Senate Health, Education, Labor and Pensions (HELP) Committee, penned a blistering letter that takes Moderna Inc. CEO Stéphane Bancel to task over the company’s plans to more than quadruple the U.S. list price of its COVID-19 vaccine once the government’s supply is depleted.
