The Joint Committee on Vaccination and Immunisation (an independent expert advisory committee that advises UK health departments on immunisation) has set out the order in which people should be vaccinated. 

The ranked prioritisation is as follows:

1. Residents in a care home for older adults and their carers
2. All those aged 80 years and over, and frontline health and social care workers
3. All those aged 75 years and over
4. All those aged 70 years and over, and clinically extremely vulnerable individuals
5. All those aged 65 years and over
6. All individuals aged 16–64 years with underlying health conditions that put them at higher risk of serious disease and mortality
7. All those aged 60 years and over
8. All those aged 55 years and over
9. All those aged 50 years and over

Care home residents began receiving vaccinations in December 2020 after further regulatory approval was granted to break down the packs of 975 doses of vaccine into smaller packs for easier transportation.

Following the announcement that a new, more transmissible strain of COVID-19, is circulating in the UK, the JCVI advised prioritising the first vaccine dose with the second dose administered up to 12 weeks later.
