//I doubt these measures are done to 'stuff' anyone else rather to safeguard the already overstretched services.//
They're being done because there is an outbreak of the Indian variant in these places and its spread has been caused by (1) People travelling back to the UK from "Red" countries and refusing to quarantine, (2) Multi-generational households and those in high density areas refusing to be vaccinated when they are eligible. A passage from a BBC report:
"But there is one stumbling block. In Bolton, the areas with the highest infections over the last week map very closely to areas with the lowest vaccination rates."
These areas (where, in some, less than 60% of the population over 40 has received their first jab) are in the centre of the Bolton area. The argument that these people are stuck out in the sticks with no suitable transport is specious. The vast majority of those hospitalised in that area have not been vaccinated, despite being eligible.
So the lesson is, avoid having your vaccination if it is a tad inconvenient and wait for an outbreak to occur which threatens your area. They'll then either send a bus round to carry out the vaccination at the end of your street or they might even come to your house and vaccinate everybody to save you the bother of going out at all.
