Summary
Brief summary
Despite the greater risk of adverse COVID-19 outcomes, antibody and cell-mediated immune
responses to COVID-19 vaccines vary amongst immunocompromised (IC) people and are poorly
defined. IC hosts were largely excluded from the COVID-19 vaccine registration trials, though
many countries recommend additional and booster doses of vaccination in this group.

BOOST-IC is an adaptive randomised clinical trial (RCT) to assess the immunogenicity and
safety of additional COVID-19 vaccine doses in immunocompromised (IC) people, including
people with HIV, solid organ transplants (SOT) recipients or those with haematological
malignancies. Briefly, the study aims to generate high-quality evidence on the immunogenicity
and safety of alternative COVID-19 booster strategies against SARS-CoV-2 for IC people in
Australia.
