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

Experimental: Administration of Booster Dose study participant will receive either 30ug in 0.3 ml of Pfizer/BioNTech (BNT162b2) or 0.25 ml of Moderna vaccine administered intramuscularly. |
Biological: Pfizer/BioNTech (BNT162b2)
participants will receive a booster dose (1st booster or 2nd booster) of vaccine
Biological: Moderna
participants will receive a booster dose (1st booster or 2nd booster) of vaccine

Outcome Measures
Primary Outcome Measures
- Number of participants infected with SARS-CoV-2 after booster Dose [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.
- Levels of anti-SARS-CoV-2 IgG antibody titers after booster [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
Secondary Outcome Measures
- Measure rate of decline of immune responses [24 months]
Determine the rate of decline of immune responses in various cohort of recipients with similar co-morbidities by conducting cohort analysis
- Identify differences in immune responses based on comorbidity status [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
