COVID-19 immunity study for hospital staff and patients

This study looks at how your immune system responds to COVID-19 or the flu. It may help researchers understand these infections better, whether you are currently sick or healthy.

This study looks at how the immune system in the body responds to different COVID-19 virus variants. It may help improve how COVID-19 is diagnosed by comparing people who are currently infected and those who are not.

This study measures how many healthcare workers have COVID antibodies (proof of past infection or immune response). Results may help estimate how widespread COVID exposure has been among hospital staff.

This study looks at how the body's immune system reacted to COVID-19 in people who had either severe or mild cases. The goal is to learn more about a specific part of the immune response (called IFN-I) to better understand the disease.

This study gathers information about healthcare workers (adults) and tracks your past COVID-19 infection and vaccination history. It may help researchers understand how COVID affects healthcare workers and how vaccines relate to infection outcomes.

This study follows adults who are in the hospital (including the emergency ward) with a confirmed COVID-19 infection. It aims to learn how COVID-19 affects people in the hospital and how different cases may differ over time.
