[{"arm_notes": "", "treatment_id": null, "treatment_name": "Immune responses in kidney transplant and dialysis patients are compared in each case with that of a close household contact (usually a spouse) over the age of 18.This study is interventional in so much as close household contacts of transplant and dialysis patients will; in some instances; receive their vaccinations earlier than they otherwise would.Both patients and cohabitants will be asked to provide up to four blood samples starting prior to-; and then up to 6 months post-; receipt of the initial ChAdOx1 nCoV-19 (Oxford-AstraZeneca) or BNT162b2 (Pfizer-BioNTech) COVID-19 vaccine. Blood samples will be collected at the Royal Adelaide Hospital by trained staff. Samples for some participants will be collected at the Queen Elizabeth Hospital or at SA Pathology collection centres as dictated by convenience. Number and timing of vaccine doses received will not differ from that of the rest of the population i.e. an initial and booster dose; 21 days apart in the case of Pfizer-BioNTech and 12 weeks apart in the case of Oxford-AstraZeneca.Participants will also be asked to provide a one-off stool sample prior to vaccination using a provided at-home collection kit. In conjunction with this; participants will be asked to complete a four-day food diary.Participation in this study will amount to four appointments for blood collection; and two visits to vaccination clinics.", "treatment_type": "TODO", "pharmacological_treatment": "TODO"}]
