Well, it's a huge job, whose logistics are formidable - not only do the vaccines have to be manufactured and distributed, so does ancillary stuff such as syringes and deep freezers. It's unavoidable that the various vax stations, although striving for best efficiency, will vary in how fast they can process their patients.

Some of my own friends in the same age group (70+) have had their jabs - I'm still waiting. Not a problem.
