Under the government's priority list for the vaccine roll-out, the first doses are intended to be given to elderly care home residents and their carers, followed by people over 80 and health service staff.
The 94-year-old monarch and her 99-year-old spouse are likely to be among the first to be offered a jab, with the government prioritising elderly people as it begins the rollout of the Pfizer vaccine that was approved on Dec. 2.
