MIL who is housebound and in her nineties, has not yet been offered a booster. Just wondering what others' experiences have been. As I understand it, using Pfizer for home visits is problematic because there's a limit on the number of times the vaccine can be moved. MIL had AZ for her first two jabs, but my understanding is that the plan is to use Pfizer or Moderna for the boosters, so not sure what the plan is re people who are housebound.
