Long-term Immune Protection in COVID-19 Patients
The overall goal of the study is to identify the mechanism of response of our immune system to the novel coronavirus, severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2).
The specific objectives are to:
* Test patients' ability to neutralize the SARS-CoV-2 by measuring circulating antibodies;
* Study memory immune cells that offer long-term protection; and
* Compare the short and long-term immune responses to SARS-CoV-2 infection and vaccination.

For the COVID-19 positive and negative cohorts, paticipant's antibodies are tested approximately 14 days after the onset of symptoms (baseline), 6 months and 1 year later. For the COVID-19 vaccinated cohort, antibody testing will be conducted up to 5 times: baseline (pre-vaccination), 3 weeks after first vacinnation, 3 weeks after second vaccination, 6 months and 12 months post-vaccination.
