Exclusion criteria

Exclusion criteria: Current participant exclusion criteria as of 22/10/2024: 1. Any clinical condition that in the opinion of the investigator might pose additional risk to the participant due to participation in the study. 2. History of reaction or hypersensitivity likely to be exacerbated by any component of the study intervention including allergic reaction to any component of any of the study vaccines, known reactions related to study vaccines e.g. history of myocarditis, GuillainBarre Syndrome. 3. Unstable medical condition on the day of enrolment as determined by clinical history and examination. 4. Bleeding disorders or continuous use of anticoagulation medicine, such as coumarins and related anticoagulants (i.e., warfarin) or novel oral anticoagulants (i.e. apixaban, rivaroxaban, dabigatran and edoxaban). Use of aspirin is allowed. 5. Any confirmed or suspected immunosuppressive, or immunodeficient condition, based on medical history and physical examination. People living with HIV that is well controlled can be included in the study.* Those with a new diagnosis or an AIDs defining illness in the past 12 months cannot be included. 6. Use of immunosuppressive medication, ongoing, long term or planned, defined as more than 14 days in total of immunosuppressant treatments. For corticosteroids this will mean more than 14 days of prednisolone >20mg/day or equivalent. Use of inhaled, intraarticular and topical steroids is allowed. 7. Use or planned use of long-acting immune modifying drugs in the 12-month period before randomisation (e.g. infliximab). 8. COVID-19 or influenza vaccination 90 days prior to the study vaccination 9. Previous vaccination with a live herpes zoster vaccine within the past 5 years. 10. Administration of monoclonal antibodies (including those targeting SARS CoV2), immunoglobulins and/or blood products during the 3 months before the first dose of the study vaccines, up to 1 month after the last dose or planned during the study period. 11. Planning to or concurrently participate in another interventional clinical study. 12. Pregnancy, lactation or willingness/intention to become pregnant within the study period. 13. Previous participation in the ZosterFluCOV trial. *Defined as less than 50 copies/ml (convert as needed from IU/ml) on the last two occasions >3 months apart, and a CD4 over 500 when last checked.

Design outcomes

Primary

MeasureTime frame
Current primary outcome measure as of 22/10/2024: Immunogenicity: 1. Immunogenicity, measured by S-binding total Ig, 1 month after COVID-19 vaccine given alone compared to coadministration with RZV (first or second dose) 2. Immunogenicity, measured by haemagglutination inhibition assay (HAI), 1 month after aQIV for all four strains included in the vaccine given alone compared to coadministration with RZV 3. Immunogenicity of two doses of RZV vaccine, measured by total antibody against glycoprotein E (total anti-gE antibody concentrations) measured by enzyme-linked immunosorbent assay (ELISA), 1 month after the second dose, given alone, compared to coadministration with COVID-19 vaccine or aQIV with either the first or second dose of RZV Safety: 1. Rate of grade 3 and 4 solicited systemic adverse reactions (SSR) recorded over 7 days after 1st and 2nd doses of RZV given alone compared to coadministration with COVID-19 vaccine 2.
