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.

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.

After comparing the response to the two types of vaccines for the respiratory syncytial virus (RSV) based on its fusion protein (F), prefusion (pre-F) versus postfusion (post-F) vaccines, scientists at the National Institutes of Health (NIH) and Astrazeneca plc have demonstrated that targeting the pre-F protein led to better protection. No more bets on RSV immunization based on the post-F protein of the virus. Laboratories can now bet all on red for the pre-F technology.

Vaxxas Pty. Ltd. raised AU$34 million (US$23 million) to advance its needle-free COVID-19 vaccine program, which began in early November, and readouts from the study are expected in late February or early March, Vaxxas CEO David Hoey told BioWorld. The COVID-19 vaccine patch is based on the company’s high-density microarray patch technology that delivers Hexapro, a second-generation version of the spike protein used in all major U.S.-approved COVID-19 vaccines.
