the vaxx batch number thing

How is it possible that there are so few batch numbers?

Most batch numbers for most everything produced are done on a daily or weekly basis and include codes for factory and shift etc so if there is a problem it can be ironed out.

Even things like computer chips that have minimal batch identification will be batched by year and week of year showing a serial progression through time.

On these vaccines there would have to be more than the 30 or so 'batches' that are currently being represented. There should be hundreds or even thousands by now considering all of the different manufacturing plants and shifts etc.

Are we confusing production batch numbers with formulation numbers?

Help me out here it makes no sense.
