Remember when the vaccines first rolled out in early 21? There was a lot of extra activity showing up on military flight radar during that time and the speculation was that it was military helping with the distribution of the vaccines in an orderly fashion around the country. Back then it was thought that it was the best way to distribute the vaccine because of the special refrigeration needs of the stuff. Wonder if the batches were assigned at that point. The general 'active ingredient' stuff sent to the general public facilities (health departments, hospitals/clinics, pharmacies, etc.) and control group batches with the saline only directed to military, elected federal offices, etc.
