Any potential COVID-19 booster programme should be offered in 2 stages:
Stage 1. The following persons should be offered a third dose COVID-19 booster vaccine and the annual influenza vaccine as soon as possible from September 2021:
adults aged 16 years and over who are immunosuppressed
those living in residential care homes for older adults
all adults aged 70 years or over
adults aged 16 years and over who are considered clinically extremely vulnerable
frontline health and social care workers
Stage 2. The following persons should be offered a third dose COVID-19 booster vaccine as soon as practicable after stage 1, with equal emphasis on deployment of the influenza vaccine where eligible:
all adults aged 50 years and over
adults aged 16 to 49 years who are in an influenza or COVID-19 at-risk group. (Refer to the Green Book for details of at-risk groups)
adult household contacts of immunosuppressed individuals
As most younger adults will only receive their second COVID-19 vaccine dose in late summer, the benefits of booster vaccination in this group will be considered at a later time when more information is available. The initial objective for winter 2021 to 2022 is for persons in booster stages 1 and 2 to receive their influenza and COVID-19 vaccines in good time.
