Evaluation of COVID-19 Vaccines Given as a Booster in Healthy Adults in Indonesia (MIACoV Indonesia)
A Randomised Controlled Trial to Assess the Immunogenicity, Safety & Reactogenicity of Standard Dose Versus Fractional Doses of COVID-19 Vaccines (Pfizer-BioNTech, AstraZeneca or Moderna) Given as a Booster Dose After Priming With Coronavac or AstraZeneca in Healthy Adults in Indonesia
This is a randomised controlled clinical trial to determine the reactogenicity and immunogenicity of booster doses of SARS-CoV-2 vaccines (Pfizer-BioNTech, AstraZeneca or Moderna) in adults who have previously received either AstraZeneca or Coronavac as their primary doses.
Both fractional and standard doses of Pfizer-BioNTech, AstraZeneca and Moderna will be tested.

Conditions
Detailed Description
There will be a total of 800 participants in the study, to be randomised and administered booster doses in this study.
The study will be conducted at 3 clinics in Bandung. Participants will have previously received primary doses of Coronavac or Astranzeneca, with the second dose administered at least 6 months previously.
Participants will be followed for 12 months following the booster vaccine adminstration, with blood samples drawn at baseline, 28 days, 6 months and 12 months following booster vaccine administration.

The primary endpoint is the seroresponse rate at the Day-28 visit.
The Seroresponse rate at the individual level is defined as either a ≥4-fold rise in binding antibodies at the Day-28 visit compared to baseline (pre-vaccination) with a titre of <200 BAU/ml, a ≥2-fold rise among participants with a baseline (pre-vaccination) titre of >≥200 BAU/ml, or ≥4 times the lower limit of detection if baseline levels are lower than the limit of detection.
