COVID-19 Vaccine Response in Chronic Respiratory Conditions

COVID-19 Vaccine Response and Durability In Patients With Chronic Respiratory and Medical Disorders

The investigators will assess the antibody, T cell and B cell responses to SARS-CoV-2 vaccination before and every 3 months for 18 months after the initial vaccination or subsequent vaccinations (boosters) in adults and children including patients with chronic medical conditions.

HYPOTHESES

1. Patients with chronic respiratory diseases will have a lower antibody response to SARS-CoV-2 virus after vaccination and shorter durability of the response than control subjects without chronic disorders.
2. Patients on corticosteroids and other immunomodulator medications for chronic medical disorders will have a lower antibody response to SARS-CoV-2 after vaccination and shorter durability of the response than subjects with chronic disorders who are not being treated with corticosteroids and immunomodulator medications.

SPECIFIC AIMS

1. Enroll up to 1,000 patients receiving a SARS-CoV-2 vaccination (initial or subsequent vaccinations) in an observational study to determine vaccine antibody response and durability.

   1. Obtain blood samples to measure antibody assess the antibody, T cell and B cell responses to SARS-CoV-2 vaccination before and every 3 months for 18 months after the initial vaccination or subsequent vaccinations (boosters) .
   2. Categorize patients by their age, gender, race, ethnicity, underlying chronic disease, disease severity, medical therapy and comorbidities.
   3. Assess the clinical effectiveness of the vaccine to prevent COVID-19 infections.

3. Determine the clinical features and gene expression of patients who are less responsive (have lower antibody levels and shorter duration of antibody response) to SARS-CoV-2 vaccinations.
