People with immunocompromising conditions are strongly recommended to receive influenza vaccine every year
People aged ≥6 months who are immunocompromised are strongly recommended to receive annual influenza vaccine.
Immunocompromising conditions include:
- functional or anatomical asplenia, which includes sickle cell disease or other haemoglobinopathies, congenital or acquired asplenia, and splenic dysfunction
- chronic steroid use
People who are immunocompromised have an increased risk from influenza (see Vaccination for people who are immunocompromised).9,10 These people may have a reduced immune response to influenza vaccine, but vaccination gives them some protection.11
If a new influenza virus strain is circulating in the community, cross-protective immunity in the population may be low. For example, this occurs during an influenza pandemic. In these situations, people who are immunocompromised are recommended to receive 2 doses of inactivated influenza vaccine, at least 4 weeks apart, regardless of their previous influenza vaccination history. This helps achieve an optimal immune response.12
People with HIV
People with HIV who have minimal symptoms and high CD4+ T-lymphocyte counts develop protective antibody titres after influenza vaccination.
People with advanced HIV disease and low CD4+ T-lymphocyte counts may not develop protective antibody titres after influenza vaccination.
Influenza vaccine reduces the incidence of influenza in people with HIV.
