PROSPECTIVE OPEN LABEL CLINICAL TRIAL TO ADMINISTER A BOOSTER DOSE OF PFIZER/BIONTECH OR MODERNA COVID-19 VACCINE IN HIGH-RISK INDIVIDUALS

March 14, 2022 updated by: Sohail Rao, DHR Health Institute for Research and Development
The recent rise in infections with the Omicron variant of the SARS-CoV-2 is alarming. Equally disconcerting is the fact that individuals who were previously vaccinated (< 6 months) and have co-morbidities that are considered high risk, are getting re-infected...a process referred to as "breakthrough". There is some evidence that in these high risk individuals, the gradual decrease in immunity against the virus as depicted by a drop in anti-SARS-CoV-2 antibodies, is responsible (partially or wholly) for this reinfection. In this study, we intend to give a booster does Pfizer/BioNTech and/or Moderna and ascertain the levels of antibodies at various times pre and post vaccination. The incidence of infection with SARS-CoV-2 after booster vaccination will also be obtained.

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Number of participants infected with SARS-CoV-2 after booster Dose
Time Frame: 24 months
Determine effectiveness of booster dose in the prevention of SARS-CoV-2 Infection by assessing if subjects remain free from infections with SARS-CoV-2 after receiving booster dose.
24 months
Levels of anti-SARS-CoV-2 IgG antibody titers after booster
Time Frame: 24 months
Determine the anti-SARS-CoV-2 IgG antibody titers using a semi quantitative method at various time points (Baseline/Day 0, Day 14, Week 12 and Week 24 after booster) to assess for sustained levels of relatively high titers of anti-SARS-CoV-2 IgG in the blood of the subjects
24 months

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Measure rate of decline of immune responses
Time Frame: 24 months
Determine the rate of decline of immune responses in various cohort of recipients with similar co-morbidities by conducting cohort analysis
24 months
Identify differences in immune responses based on comorbidity status
Time Frame: 24 months
Identify differences in immune responses based on comorbidity status (e.g., Immune response in recipients with metabolic diseases vs. patients with immunosuppression) by using questionnaires
24 months
