Many people take medication that suppresses their immune system, including for the treatment of cancer, severe asthma, auto immune diseases, or following organ transplantation. Others have medical conditions that can affect the immune system, such as HIV infection, kidney failure, those with pre-existing heart conditions including (non-acute) rheumatic heart disease, congenital heart disease or a history of Kawasaki disease. People with nervous system disabilities (like cerebral palsy) and diabetes (type 1 or type 2) are also recommended to have their COVID-19vaccinations.
These conditions put people at increased risk from COVID-19,and although they may not respond as strongly to the vaccine as someone with a fully functioning immune system, it is safe for them to receive the COVID-19vaccine and it will provide some protection against COVID-19, particularly against severe, life-threatening infection.
It is important and safe for those receiving active treatment with immunosuppressive medications to have the COVID-19 vaccine. It is important that the optimal timing for vaccination is discussed with specialist before the vaccine appointment. Ideally, vaccination should be conducted prior to any planned immunosuppression.

As part of the primary schedule, a third dose of Comirnaty is recommended for people aged from 5 years who were severely immunocompromised in proximity to their first or second primary doses. For further detail see the Immunisation Handbook 2020 Chapter 5 (section 5.5.8). Prescription and written consent are needed for third primary doses.
Preferably, the third dose should be administered at least eight weeks after the second dose. However, the timing also needs to consider current or planned immunosuppressive therapies.
If there are current or planned immunosuppressive therapies, aim to delay the third dose of vaccine until two weeks after the period of immunosuppression, in addition to the time period for clearance of the therapeutic agent.
The eligibility criteria to get a third primary dose is complex. It only applies to people who are severely immunocompromised. See Table 5.3 of the Immunisation Handbook 2020. This list is not exhaustive but provides guidance on scenarios where three primary doses are recommended. There is variation between individuals in response to immunosuppressive or immunomodulating therapy. Clinicians may use their judgement for conditions or medications that are not listed here that are associated with severe immunocompromise.
If an alternative to Comirnaty is required or requested, the second line COVID-19 vaccine Nuvaxovid can be given as a third primary dose to those aged 18 years or older. This also requires a prescription and written consent.
Evusheld is a pre-exposure prophylaxis (PrEP) therapeutic treatment containing two long-acting monoclonal antibodies (tixagevimab and cilgavimab). It was indicated for protection of highly immunocompromised people but is now not recommended as it does not provide adequate protection against most of the currently circulating SARS-CoV-2 variants.
