We never had any shortages during previous outbreaks. It won’t be a case of 65 million people being immunised in one go. Vaccination will go on for more than a year. The Pfizer shot is two jabs, 4 weeks apart. Its high unlikely that priority goups 8 thru 11 will get this Pfizer or Moderna vaccine.
1962, Bradford Smallpox Outbreak
Note, the vaccination process was a little involved.
Its really not rocket science.
Back then, people queued, maybe all day. Now, we’ll probably get a text with an appointment and place to go, or even select a time convenient to you. Some vaccines might be delivered by aerosol, or through a needless syringe.
