Detaljert beskrivelse
This is an open-label uncontrolled study in which all participants will receive two doses of the inactivated adsorbed vaccine against COVID-19, and will be followed up for safety and immunogenicity analysis for 24 months. This study will assess safety and immunogenicity of the inactivated vaccine adsorbed against COVID-19 (CoronaVac) in a population of healthy individuals older than 18 years of age.
The estimated number of participants is 1200. Participants will be recruited within 3-4 months. The total duration of the study is estimated to be 30 months after recruitment begins.
The participants will remain in the study for approximately 24 months. The study will be carried out at the clinical research center of the D'Or Institute for Research and Education (IDOR) located at the Hospital Glória D'Or, in the city of Rio de Janeiro, RJ, Brazil

Beskrivelse
Inclusion Criteria:
- Adults 18 years of age or older;
- Agree with study procedures after reading and signing the Informed Consent Form
Exclusion Criteria:
- Pregnancy (confirmed by positive β-hCG test), breastfeeding and / or expressing intention to have sexual practices with reproductive potential without using contraceptive methods in the three months following vaccination
- Evidence of uncontrolled neurological, cardiac, pulmonary, hepatic or renal disease, according to anamnesis or physical examination. Significant changes in treatment or hospitalizations due to worsening of the condition in the last three months are indicators of uncontrolled disease;
- Diseases with impaired immune system including: neoplasms (except basal cell carcinoma), congenital or acquired immunodeficiencies and autoimmune diseases not controlled according to anamnesis or physical examination. Significant changes in treatment or hospitalizations due to worsening of the condition in the last three months are indicators of uncontrolled disease;
- Behavioral, cognitive or psychiatric illness that, in the opinion of the principal investigator or his medical representative, affects the participant's ability to understand and collaborate with the requirements of the study protocol
- Any alcohol or drug abuse in the last 12 months prior to inclusion in the study that has caused medical, professional or family problems, as indicated by clinical history;
- History of severe allergic reaction or anaphylaxis to the vaccine or components of the study vaccine;
- History of asplenia;
- Participation in another clinical trial with product administration under investigation during the six months prior to its inclusion in the study or scheduled participation in another clinical trial in the two years following inclusion;
- Previous participation in a COVID-19 vaccine evaluation study or previous exposure to a COVID-19 vaccine;
- Use of immunosuppressive therapies six months prior to inclusion in the study or its scheduled use within two years of inclusion. Immunosuppressive therapies will be considered: antineoplastic chemotherapy, radiation therapy, immunosuppressants to induce tolerance to transplants, among others.
- Have received an immunosuppressive dose of corticosteroids in the last three months prior to inclusion in the study or scheduled administration of an immunosuppressive dose of corticosteroids for the three months following inclusion in the study. The dose of corticosteroids considered immunosuppressive is equivalent to prednisone at a dose of 20 mg / day for adults, for more than a week. The continuous use of topical or nasal corticosteroids is not considered immunosuppressive;
- Have received blood products (transfusions or immunoglobulins) in the last three months before inclusion in the study, or scheduled administration of blood products or immunoglobulin in the two years following inclusion in the study;
- Suspected or confirmed fever within 72 hours prior to vaccination or axillary temperature greater than 37.8 ° C * on the day of vaccination (inclusion may be postponed until the participant completes 72 hours without fever);
- Possible or confirmed case of COVID-19 on the day of vaccination (vaccination can be postponed until the participant completes 72 hours without symptoms or the diagnosis is ruled out);
- Have received vaccine with live attenuated virus in the last 28 days or inactivated vaccine in the last 14 days prior to their inclusion in the study, or have immunization scheduled for the first 28 days after their inclusion in the study;
- History of bleeding disorders (for example, deficiency of clotting factors, coagulopathy, platelet dysfunction), or previous history of bleeding or significant bruising after IM injection or venipuncture.
- Any other condition that, in the opinion of the principal investigator or his medical representative, could jeopardize the safety or rights of a potential participant or that would prevent him from complying with this protocol.
