Interesting that POTUS has been calling Pfizer out recently- tweet related. Lot of common medications have been on back order recently.
The link below appears to be a reasonable example of which you can scan some meds recently off the shortage list.
Pfizer has a large footprint. But it seems like they are over represented on this list as I started randomly spot checking.
Frequently citing manufacturing delay by Pfizer. With all I've seen vaccine/medication related concerns, the increased number of unavailable/short supply meds catch my attention.
