Moderna reports next-gen COVID shot effective in trial

Moderna has announced that its next-generation COVID-19 vaccine, mRNA-1283, has successfully completed a Phase 3 clinical study, showing improved effectiveness for adults. The new vaccine, which targets newer strains of coronavirus that have emerged since the company’s original vaccine, Spikevax, was developed, performed at least as well as its predecessor. Notably, the new vaccine demonstrated stronger effects in individuals aged 18 and older, according to statements released by the company on Thursday. Moderna plans to consult regulatory authorities to discuss the subsequent steps for the vaccine. The detailed results from the Phase 3 trial, which involved 11,400 participants aged 12 and over, will be presented at an upcoming medical conference.

The introduction of this new vaccine is a pivotal element of Moderna's strategy for growth, especially as sales of its original COVID-19 vaccine have begun to decline. The new vaccine offers several advantages over the original. One significant improvement is its stability; it is designed to be refrigerator-stable, which extends its shelf life and simplifies both distribution and administration processes. Previously, the company had reported that the new vaccine elicited a stronger immune response compared to the original vaccine.

In addition to its standalone benefits, the new vaccine is also part of an experimental combination vaccine aimed at combating both COVID-19 and influenza. This combination vaccine has recently yielded positive results in studies and presents the possibility of a single annual vaccination for both viruses. This could be particularly convenient for patients who are already accustomed to receiving their flu shots each fall.

Despite the COVID-19 pandemic no longer dominating public concerns, the virus continues to exist and evolve. Vaccine manufacturers, including Moderna, are preparing to update their formulations following recent recommendations from the Food and Drug Administration (FDA) advisers. These advisers have suggested that new vaccine formulations should address yet another family of coronavirus strains.

Looking beyond COVID-19, Moderna is expanding its horizons by developing vaccines for other diseases. The company is gearing up to launch a new vaccine for respiratory syncytial virus (RSV) and is also involved in advanced testing of a cancer vaccine in partnership with Merck.

In summary, Moderna's new mRNA-1283 COVID-19 vaccine has shown promising results in a Phase 3 trial, particularly among adults. With enhanced stability and a higher immune response, it represents a significant advancement over the original Spikevax vaccine. The company's broader strategy includes the development of combination vaccines and new products for other diseases, positioning Moderna to maintain its relevance and growth in the evolving healthcare landscape.
