Participate in a compensated research study that will help researchers at the NIH understand how previous dengue infection impacts vaccine responses. Did you know that millions of cases of dengue infection occur worldwide each year? Dengue fever (also called dengue hemorrhagic fever) is a mosquito-borne illness that occurs in tropical and subtropical areas of the world. A severe case of dengue fever can cause serious bleeding, a sudden drop in blood pressure, or death. By taking part in our research study, you can help us make better dengue vaccines that may be used to prevent the virus. Join our compensated study today! |
