You're probably referring to the Strategic National Stockpile. There are approximately 55 million doses of Tamiflu on hand as of earlier this year, though the ASPR generally keeps this number under its hat. In the meantime, there is an H5N1 candidate vaccine, and it would probably be able to get to market fairly quickly (compare with the H1N1 vaccine rollout in 2009).
My understanding is that there is also some stockpiled H5 vaccine from years ago. Supposedly it's not a perfect match for the current strain going around in cattle but it's pretty good.
Yeah the government has been heavily ramping up production of influenza antigen that should be effective against this strain the past year of so and funding more targeted mrna type vaccine research for h5n1
we won't be as blindsided or unprepared as we were by covid for this one
