Study on an Investigational Yellow Fever Vaccine Compared With YF-VAX in Adults in the USA
Active Not Recruiting
The primary objective of the study is to demonstrate the non-inferiority of the antibody response in terms of seroconversion rate 28 days after vaccine administration of one dose of yellow fever vaccine (vYF) compared to the antibody response after one dose of the YF-VAX control vaccine in yellow fever naïve participants. The secondary objectives of the study are: * To describe the immune response to yellow fever in both vaccine groups before and after vYF or YF-VAX administration. * To descri... Read More
