COVID-19 vaccine responses in PIDD subjects

Purpose of this Study

We are doing this study to learn more about the immune response patients with X-linked Agammaglobulinemia (XLA) have to COVID-19 vaccination. We will compare their immune responses to those of healthy people who have normal immune systems. Better understanding of cellular responses to COVID-19 vaccines by XLA patients is important since XLA patients cannot make antibodies to vaccines. If you are interested, please contact the study team at XLACOVIDvax@duke.edu.

Who Can Participate?

Eligibility

People with XLA and healthy male participants are both eligible to join this study. We are enrolling XLA patients who:
  • Are diagnosed with XLA based on absence of B cells or genetic confirmation
  • Are being treated with immunoglobulin replacement without recent dose change
  • Have not received a COVID-19 vaccine, but plan to get one
  • Have no signs or symptoms of COVID-19 infection
  • Have not received any other vaccines within 2 weeks of the COVID-19 vaccine
We are enrolling healthy male participants who:
  • Are 12 years and older
  • Have not received a COVID-19 vaccine, but plan to get one
  • Have no signs or symptoms of COVID-19 infection
  • Do not have any medical conditions that affect the immune system
  • Are not taking any medicine that affects the immune system
  • Have not received any other vaccines within 2 weeks of the COVID-19 vaccine
