THIS STUDY IS IN FOLLOW UP
What is the purpose of this study?
This study asks for human blood donations to help with the development of vaccines to prevent infectious diseases. We need human blood to understand the immune response to infection and to test promising new vaccines against infectious diseases in the laboratory. Our blood is made up of many parts, but the component we are interested is called Complement. Complement is a collection of proteins that help antibodies kill their target bacteria more effectively. The purpose of the study is to (a) find people who have the type of Complement we can use in the laboratory research we do, and (b) are willing to give blood samples to support our work. The samples would be used in the laboratory analysis of clinical trials of vaccines used in adults and children, and some samples in pre-clinical (animal) experiments testing new vaccines before they enter human-stage testing.
