Sampling MethodProbability Sample
Study Population

The study will include 156 male or female participants aged between 18 and 65 years, with complete primary vaccination for COVID-19 and at least one booster dose, the last being carried out with the Comirnaty Bivalent BA.4/BA vaccine. 5.

You may qualify if:

  • Male or female.
  • Age from 18 to 65 years old, inclusive.
  • Body mass index (BMI) between 19.0 and 35.0 kg/m2, inclusive.
  • Female participant with a negative pregnancy test on the day of vaccination.
  • Consent form voluntarily signed before any procedure.

You may not qualify if:

  • Confirmation of active SARS-CoV-2 infection in rapid antigen test screening.
  • History of serious adverse reaction to any vaccine, medication or component of the investigational product.
  • History of immunodeficiency, autoimmune diseases and cardiomyopathies.
  • History of malignancy within 1 year before screening (except basal cell carcinoma of the skin or in situ carcinoma of the cervix, which have already resolved).
  • History of uncontrolled coagulopathy or blood disorders that contraindicate intramuscular injection.
  • History of uncontrolled epilepsy or other progressive neurological disorders such as Guillain-Barré Syndrome.
  • Treatment with immunosuppressive medications in the 3 months prior to the first vaccination or 6 months for chemotherapy.
  • History of systemic steroids (prednisone ≥ 20 mg/day or equivalent for \>14 consecutive days) within 3 months prior to screening. Topical, inhaled, intranasal, and intra-articular corticosteroids are permitted regardless of dose.
  • Use of any other vaccine less than 14 days before or planning to use up to 29 days after V0.
  • Presence of tattoos, scars, skin discoloration or any other skin disorders at the injection site that, in the opinion of the investigator, may impair the assessment of local reactogenicity.
  • Any condition that, in the opinion of the investigator, endangers the safety or rights of the participant or makes the participant unsuitable for the study.
  • Clinically significant changes in safety examinations, defined as:
  • Hb ≤ 10.9 g/dL;
  • Leukocyte count \< 2500 cells/mm3;
  • Absolute neutrophil count \< 1000 cells/mm3;
  • +9 more criteria
