Title: SARS-CoV-2 longterm immunity after primary immunisation and booster vaccination of the elderly and health care workers (short title: COVIM-Boost)
Primary substudy endpoint: Immunogenicity of COVID-19 vaccination 18 months after first vaccination as confirmed by the presence of anti-SARS-CoV-2-specific antibodies, i.e. positivity in serological assay system (S1-IgG ELISA above the predefined lower detection limit).
Secondary substudy endpoints: • Immunogenicity of COVID-19 vaccination 12 and 18 months after first vaccination as confirmed by the presence of anti-SARS-CoV-2-specific antibodies, i.e. positivity in serological assay system (S1-IgG ELISA above the predefined lower detection limit) • Immunogenicity of COVID-19 vaccination 12 and 18 months after first vaccination as confirmed by the presence of SARS-CoV-2 -specific CD4+ T cells • Immunogenicity of COVID-19 vaccination 12 and 18 months after first vaccination as confirmed by the presence of neutralizing antibodies against SARS-CoV-2 wildtype • Immunogenicity of COVID-19 vaccination 12 and 18 months after first vaccination as confirmed by the presence of neutralizing antibodies against different PANGO lineages of SARS-CoV-2 (e.g., B.1.1.7, B1.351, P.1, B.1.617.2) • Proportion of participants with symptomatic SARS-CoV-2 infection • Differences in humoral and cellular immunogenicity at 12 and 18 months after first vaccination in HCWs and elderly • Differences in humoral and cellular immunogenicity after different vaccine regimen (vaccine schedule, vaccine type, combination of vaccines), particularly between homologous and heterologous prime-boost regimen at 12 and 18 months after first vaccination in HCWs and elderly • Change in acceptance and adherence to the use of non-pharmacological measures (nPM) after vaccination or booster vaccination against COVID-19 • Safety and tolerability of booster vaccination • For participants having received booster vaccination: - Immunogenicity of booster vaccination 4 weeks (± 1 week) after boost as confirmed by the presence of anti-SARS-CoV-2-specific antibodies, i.e. positivity in serological assay system (S1-IgG ELISA above the predefined lower detection limit) - Immunogenicity of booster vaccination 4 weeks (± 1 week) after boost as confirmed by the presence of SARS-CoV-2 -specific CD4+ T cells - Immunogenicity of booster vaccination 4 weeks (± 1 week) after boost as confirmed by the presence of neutralizing antibodies against SARS-CoV-2 wildtype - Immunogenicity of booster vaccination 4 weeks (± 1 week) after boost as confirmed by the presence of neutralizing antibodies against different PANGO lineages of SARS-CoV-2 (e.g., B.1.1.7, B1.351, P.1, B.1.617.2) - Differences in humoral and cellular immunogenicity after different booster regimen (including neutralizing antibodies against different PANGO lineages of SARS-CoV-2 (e.g., B.1.1.7, B1.351, P.1, B.1.617.2)), particularly between homologous and heterologous boost vaccination, at 12 and 18 months after first vaccination in HCWs and elderly
Explanatory statement: In the context of protocol version 1.6 (dated 09.12.2021), it was decided to conduct COVIM-Boost as a separate study (in accordance with § 4 (7a) MedBVSV) and thus to terminate the substudy COVIM-Boost together with the main study. An analysis of the endpoints is therefore mainly performed as part of the analysis of the separate study.

E.4 | Principal exclusion criteria |
An individual who meets any of the following criteria will be excluded from participation in this study:
- Any contraindications for SARS-CoV-2 vaccination (according to SmPCs) - Refusal to participate. - Participants unwilling or unable to consent to saving and propagation of pseudonymized medical data for study reasons. - Persons who are legally detained in an official institution - Persons who might be dependent on the sponsor, the investigator or the trial site. This exclusion criterion does not apply for cohort 1 (HCWs), as it is necessary for this population to participate. In order to assure that no pressure to participate is put on them, the recruitment procedure of HCWs must follow the respective SOP of the sponsor. |
