WHO and regulators want to change the flu vaccine
The WHO and some drug regulators want flu vaccine makers to quickly remove a component from the shots called B/Yamagata. They say that this targets a lineage of flu B viruses that went extinct during the Covid-19 pandemic: "There's no [B/Yamagata] virus circulating, so why include the antigen?" one influenza expert told STAT. It's actually a matter of safety — many flu vaccines contain live but weakened forms of the virus. There's the potential that the attenuated B/Yamagata virus could reseed the strain in the world.
But that's easier said than done, and some say it'll take until the 2025-2026 vaccine cycle to accomplish the reconfiguration. In some countries, the regulatory pathway to make such changes is complex and time-consuming. About 170 regulatory agencies will have to sign off on a cumulative 1,500 vaccine variations that need to be made to existing licenses.

Docs in dark about FDA approval processes
Many physicians have little understanding of how drugs and devices are regulated in the U.S. In a recent survey published in Health Affairs, only 17% of physicians felt they understood the FDA's device approval process, and 41% understood the drug approval process. Researchers at UCSF are trying to close this gap.
"We really want to make sure docs understand FDA regulation because they're the ones with the pen to write prescriptions to recommend devices, and they need to be able to adequately advise patients about the benefits and harms of these therapies," one of the study's authors told STAT.
This could be as simple as dedicating a few hours of medical school to teaching the outlines of the U.S. regulatory pathway. Then, as physicians progress to residency and fellowships, they could be taught the intricacies of regulating the devices they would use in their practice.
