    It's H1N1, after all, so I'm not talking about the underlying technology.

    But you don't recycle the eggs, for example, from last season's trivalent production.  

    Any time there's new materials brought into any 'same old process', there exists an opportunity to contaminate resource streams, or bring in production lots of growth media, etc. that differ simply because they're different production lots.

    Just one hypothetical example and trying to account for their gearing processes up to address pandemic quantity production levels.  

    One more, however, as my understanding is that trivalent vaccine production begins life earlier in the typical timespan of the flu season, no, and would provide for a longer window of testing?  What's the normal seasonal testing cycle/regime?

    But, you're the specialist and I'd guess you get more directly from the production front-lines than I from obsessive report-tracking.

    Thanks!

      but not different from year to year, since you never recycle eggs.

      What we were told is what turned out to be... from the April 21st description until October availability, it took six months.

      Safety tests are run each year, and then FDA licences the vax. Same process, same time frame, only shifted. Trivalent vax is recommended in Feb, then started and available Sept, so very similar time frame.

        of the seasonal candidate selections.  The cycles are more closely aligned than I was accounting for in pandemic vs. seasonal.
