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.

Conditions
Outcome Measures
Primary Outcomes (2)
Number of participants infected with SARS-CoV-2 after booster Dose
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
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 Outcomes (2)
Measure rate of decline of immune responses
24 months
Identify differences in immune responses based on comorbidity status
24 months
Study Arms (1)
Administration of Booster Dose
EXPERIMENTALstudy participant will receive either 30ug in 0.3 ml of Pfizer/BioNTech (BNT162b2) or 0.25 ml of Moderna vaccine administered intramuscularly.
Interventions
participants will receive a booster dose (1st booster or 2nd booster) of vaccine
participants will receive a booster dose (1st booster or 2nd booster) of vaccine
