Trial design
CTIS Part I — objectives, methods, condition coding
Main objective
Scope: Prophylaxis, Pharmacodynamic
Determine the effect of the time of day of influenza vaccine administration on influenza vaccine strain-specific serum antibody titers 28 days (+/- 3 days) after vaccination in adults aged 60-85 years.
Secondary objectives 4
- Determine the effect of the time of day of influenza vaccine administration on influenza-specific T cell responses 28 days (+/- 3 days) after vaccination in adults aged 60-85 years.
- Determine the optimal time of day for administering the influenza vaccine to induce the strongest vaccine strain-specific antibody and T cell responses in adults aged 60-85 years.
- Determine the association between chronotype and both the vaccine-induced immune response and optimal vaccination time.
- Determine the effect of the time of day of influenza vaccine administration on the incidence of influenza virus infection and self-reported ILI symptoms up to six months of follow-up.

Eligibility criteria
Principal inclusion / exclusion criteria as submitted by sponsor
Inclusion criteria 4
- Aged 60-85 years at the time of inclusion.
- Willing and able to come to the vaccination location at a randomly assigned timeslot.
- Available for the follow-up period of 6 months.
- Have provided written informed consent.
Exclusion criteria 10
- Known or suspected allergy to any of the vaccine components or having experienced a previous severe adverse reaction to any vaccine.
- Present evidence of serious diseases demanding either regular use of oral immunosuppressive medical treatment, like corticosteroids, three months prior to study enrolment, or demanding acute use of high dose oral immunosuppressives two weeks prior study to study enrolment.
- Receipt of an organ- or bone marrow transplant
- Receipt of chemotherapy in the previous year.
- Receipt of blood products or immunoglobulins, within 3 months before study entry.
- Known or suspected immunodeficiency, auto-immune disease, any type of cancer.
- Known to be positive for human immunodeficiency virus, and/or hepatitis C virus and/or hepatitis B virus.
- Receipt of any vaccine(s), including the COVID-19 vaccine, less than two weeks prior to or within one month after baseline.
- Receipt of influenza 2024/2025-season vaccine prior to or within one month after baseline.
- Known to have an increased susceptibility to bleeding (bleeding diathesis), and are therefore not suitable for intramuscular vaccination.
Endpoints
Primary and secondary outcome measures (English text)
Primary endpoints 1
- The increase in influenza vaccine strain-specific serum antibody titers from pre-vaccination (T0) to 28 days (+/- 3 days) post-vaccination (T1) as measured by HI assay.
Secondary endpoints 3
- The increase in influenza-specific T cell responses in PBMCs from pre-vaccination (T0) to 28 days (+/- 3 days) post-vaccination (T1) as measured by ELISpot.
- Chronotype, assessed via the micro-Munich Chronotype Questionnaire
- The incidence of influenza virus infection, as determined by rapid influenza diagnostic self-tests, and self-reported influenza-like illness symptoms up to six months of follow-up.
