FDA declines to review Moderna application for new flu vaccine

Moderna requests meeting to discuss refusal as decision could have implications for all new and updated vaccines

US regulators will not review Moderna's request to license a new, potentially more effective flu shot - even though the US Food and Drug Administration (FDA) previously gave the green light to the project - in a decision that could have implications for all new and updated vaccines in the US.

It's the latest move by the Trump administration against vaccines. Officials in January decided to stop fully recommending one-third of routine childhood vaccines, including flu vaccines.
