The 2024-2025 season introduces a new vaccine formula with a monovalent component designed to enhance protection against current variants and reduce severe outcomes such as hospitalization and death.

The companies’ study met 1 of their 2 primary immunogenicity objectives.

A new phase 1 clinical trial will determine if vaccine candidate, MPV/S-2P, is safe for humans, and may potentially offer protection not seen before in the first-generation of COVID-19 vaccines.

In this week’s edition of MMWR, the Centers for Disease Control and Prevention reported on the vaccines’ safety profile for each of the FDA approved immunizations and rationale for the recommended age groups.
