Overview
Brief Summary
This is a Phase II, randomized, double-blind, multi-centre trial to evaluate the safety and immunogenicity of BIMERVAX® when coadministered with seasonal surface antigen inactivated adjuvanted influenza vaccine (SIIV) in adults older than 65 years of age fully vaccinated against COVID-19.
In this study approximately 300 adults aged 65 or older will be enrolled and followed for 1 month after study treatment. Safety and immunogenicity of all participants will be assessed.
Investigators
Eligibility Criteria
Inclusion Criteria
- •Adults aged 65 or older at Day
- •Are willing and able to sign the informed consent and can comply with all study visits and procedures.
- •Participant must have received at least a primary scheme of an mRNA vaccine (2 doses). Booster doses or previous COVID-19 infections are allowed. Last dose must have been administered at least 6 months before Day
- •History of COVID-19 infection is allowed if occurred at least \>30 days before Day
- •Have a negative Rapid Antigen Test (RAT) at Day 0 before vaccinations.
- •Adults determined by clinical assessment, including medical history and clinical judgement, to be eligible for the study, including adults with pre-existing chronic and stable diseases (non-immunocompromised), if these are stable and well-controlled according to the investigator's judgment.
Exclusion Criteria
- •Acute illness with fever ≥ 38.0°C at Day 0 or within 24 hours prior to vaccination. Afebrile participants with minor illnesses can be enrolled at the discretion of the investigator.
- •Allergy to egg proteins (egg or egg products) or chicken proteins.
- •History of Guillain-Barré syndrome (GBS)
- •History of COVID-19 infection (described as a positive RAT or PCR), in the previous 30 days before Day
- •Other medical or psychiatric condition including recent (within the past year) or active suicidal ideation/behaviour that may increase the risk of study participation or, in the investigator's judgment, make the participant inappropriate for the study.
- •History of severe adverse reaction associated with a vaccine and/or severe allergic reaction (e.g. anaphylaxis) to any component of the study intervention(s).
- •Immunocompromised individuals defined as those with primary and secondary immune deficiencies and those receiving chemotherapy or immunosuppressant drugs other than steroids and glucocorticoids (maximum 30mg/day of prednisone, or equivalent, by any administration route for a maximum of 30 consecutive days), within 90 days prior to vaccination or during the study.
- •Bleeding diathesis or condition associated with prolonged bleeding that would, in the opinion of the investigator, contraindicate intramuscular injection.
- •Receipt of blood-derived immune globulins, blood, or blood-derived products in the past 3 months.
- •Participation in other studies involving study intervention within 28 days prior to screening and/or during study participation.
