Clinical Trial Summary

The goal of this open-label clinical trial is to evaluate the safety and immunogenicity of INAVAC (Vaksin Merah Putih - UNAIR SARS-CoV-2 (Vero Cell Inactivated)) Vaccine as Homologue Booster in Adult Subjects in Indonesia. The main question it aims to answer is: "To evaluate the humoral immunogenicity profile at 28 days following vaccination with INAVAC vaccine as homolog booster administered intramuscularly in healthy adults age 18 years and above". Participants will be administered one dose of vaccination for the third dose (booster vaccination) intramuscularly.

Description:

This is an open-label trial. There will be only one group in the study. This group will receive the INAVAC vaccine as a booster. The inclusion and exclusion criteria for the subjects are listed below. All subjects will be followed for 6 months. The vaccine will be administered intramuscularly. This study will have one interim and one full analysis report. A Data Safety Monitoring Board will be commissioned for this study to evaluate safety data over the study period and to review any events that meet a specific study pausing rule or any other safety issue that may arise. They will review the 7 and 28-day safety data following the vaccine, and then the 3 and 6-month safety data. The immunogenicity data will be evaluated for 6 months.

3. Known history of allergy to any component of the vaccines

4. History of uncontrolled coagulopathy or blood disorders contraindicating intramuscular injection

Subjects who have received in the previous 4 weeks a treatment likely to alter the immune response (intravenous immunoglobulin, blood-derived products, long-term corticosteroid - more than 2 weeks, and so on), OR anticipation of the need for immunosuppressive treatment within 6 months after last vaccination. The use of topical or nasal steroids will be permitted. Inhaled glucocorticoids are prohibited.

7. Unstable chronic disease, inclusive of uncontrolled hypertension, congestive heart failure, chronic obstructive pulmonary disease, asthma, chronic urticaria, and diabetes requiring the use of medicine. The final decision regarding this condition will be made by the attending field clinicians or investigators.

8. Any abnormality or chronic disease which according to the investigator might interfere with the assessment of the trial objectives

10. Subjects already immunized with any other vaccines within 4 weeks prior and expect to receive other vaccines within 60 days following the booster dose

11. Individuals who have a previously ascertained COVID-19 in 1 month (for mild, moderate, or asymptomatic people) or 3 months (for severe COVID-19) before the first recruit of this study, or in close contact in the last 14 days with a confirmed case of Covid-19.

12. Positive test for SARS-CoV-2 (Antigen or PCR) at screening before the vaccination. Testing may be repeated during the screening period if exposure to a positive confirmed case of SARS-CoV-2 is suspected, at the discretion of the investigator.

13. History of alcohol or substance abuse

14. HIV patients.

15. Malignancy patients within 3 years before study vaccination.

19. Participant has a major psychiatric problem or illness

20. Participant cannot communicate reliably with the investigator

21. Participant has contraindications to intramuscular injection and blood draws, such as bleeding disorders or phobia.
