Study Summary

Background: The immune system defends the body against disease and infection. Immune deficiencies are health conditions that decrease the strength of this response. Vaccines stimulate the immune system to create a defense against a specific type of germ. Researchers want to compare immune system responses to COVID-19 vaccines in people with and without immune deficiencies. Objective: To learn about how people with immune deficiencies respond to COVID-19 vaccines. Eligibility: People age 3 and older with an immune deficiency who plan to get a COVID-19 vaccine. Healthy volunteers are also needed. Design: Participants will be pre-screened for eligibility, including COVID-19 vaccination history and immune status. Participants will give a blood sample before they get their first COVID-19 vaccine. Blood will be drawn from an arm vein using a needle. Blood can be drawn at the NIH, at a local doctor's office, or at a laboratory. It may also be drawn through a fingerstick at home. Participants will also complete 2 online surveys about their health and COVID-19 history. Additional surveys are optional. Participants will give a second blood sample 2 to 4 weeks after they get the vaccine. They will complete 2 surveys about changes in their health and side effects from the vaccine. If participants get another COVID-19 vaccine dose, they will repeat the blood draw and surveys 3 to 4 weeks later. Participants may give 3 optional blood samples in the 24 months after their last vaccine. They may also give saliva samples every 2 weeks while they are in the study for 6 months following their last vaccine. Participation will last from 1 month to 2 years after the participant's last vaccine.
