FDA meeting to choose flu vaccine composition canceled without explanation

He said this year’s meeting had been set for March 13, and he received an email this afternoon saying it had been canceled.

He said it wasn’t clear who directed the meeting to be cancelled or why, and said it’s also not clear now how flu vaccine manufacturers will get guidance on the composition of seasonal flu vaccines – “relying on WHO recommendations? What’s the plan?” he said.

An email to the US Department of Health and Human Services seeking comment wasn’t immediately returned.
