Background: FDA cancels meeting to select flu strains for next season's shots - NBC

Will the regular winter flu shot be markedly less available than it was in the previous 2024/25 winter season?

This will be determined based on mainstream media reporting. I will not trade in this market.

I don't have objective criteria for this at the moment. I welcome suggestions but expect it will probably be subjective in the end, based on whether flu vaccine (un)availability is in the news or not.
