The JCVI published its recommendations on a COVID-19 vaccination booster programme on 14 September. You can read the full statement on the UK Government website; their key advice is as follows:

“JCVI advises that, for the 2021 COVID-19 booster vaccine programme, individuals who received vaccination in Phase 1 of the COVID-19 vaccination programme (priority groups 1 to 9) should be offered a third dose COVID-19 booster vaccine. This includes:

  • those living in residential care homes for older adults
  • all adults aged 50 years or over
  • frontline health and social care workers
  • all those aged 16 to 49 years with underlying health conditions that put them at higher risk of severe COVID-19 (as set out in the green book), and adult carers
  • adult household contacts of immunosuppressed individuals

“As most younger adults will only have received their second COVID-19 vaccine dose in late summer or early autumn, the benefits of booster vaccination in this group will be considered at a later time when more information is available. In general, younger, healthy individuals may be expected to generate stronger vaccine-induced immune responses from primary course vaccination compared to older individuals. Pending further evidence otherwise, booster doses in this population may not be required in the near term.

“JCVI will review data as they emerge and consider further advice at the appropriate time on booster vaccinations in younger adult age groups, children aged 12 to16 years with underlying health conditions, and women who are pregnant.”

The JCVI has recommended that the booster takes the form of a Pfizer jab, regardless of which vaccine was used for the first two doses. A half dose of the Moderna vaccine may be used as an alternative. Astra Zeneca may be used where mRNA vaccines (i.e., Pfizer, Moderna) cannot be used. They also recommend that at least 6 months has elapsed between the second dose and a booster dose.
