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. 

Axcella Therapeutics Inc. is working on its comeback to make something else go away. Just before Christmas, Axcella said it was repositioning itself to focus on long COVID-19 and was just granted regulatory guidance on a primary endpoint and study design from the U.K.’s MHRA to conduct a single registration trial of AXA-1125 for those with long COVID fatigue. Axcella will be meeting with the MHRA in the near term to discuss getting an innovative licensing and access pathway application, which is designed to accelerate the approval process. Axcella also has just submitted its IND to the U.S. FDA for a global phase IIb/III study for treating long COVID.

Vaxxas Pty. Ltd. and the Coalition for Epidemic Preparedness Innovations (CEPI) signed a partnership agreement to develop Vaxxas’ vaccine-patch delivery technology in a project that could end the need for frozen storage of mRNA vaccines.

In what is claimed as the largest study of how digital technologies were applied to support population level research during the pandemic, scientists at the U.K. Medical Research Council’s epidemiology unit at Cambridge University have reported high, sustained levels of engagement in a fully remote COVID-19 study that ran at a time when visits to a study center were not possible.
