I know this is an American context but you can apply it to care homes:

Some quotes to note:
"But the vaccine’s complex and super-cold storage requirements are an obstacle for even the most sophisticated hospitals in the United States and may impact when and where it is available in rural areas or poor countries where resources are tight."
""hospitals even in big cities do not have storage facilities for a vaccine at that ultra-low temperature.”
Indeed, one of the most prestigious U.S. hospitals, the Mayo Clinic in Rochester, Minnesota, said it does not currently have that capability."
"The detailed plan includes using dry ice to transport frozen vaccine vials by both air and land at their recommended temperatures for up to 10 days, she said."
So some conclusions:
- it would be tough to store them, especially in care homes and GP surgeries
- it would be tough to transport (due to the need of dry ice)
- one batch would be need to be used within 10 days (I am not a vaccine expert so I don't know if that's relatively short or long)
While I understand your point about shielding - coronavirus is a pooled risk as Van Tam said in a press conference - there are logistical reasons with the rollout of the vaccine. Though the rollout will be interesting...
