Message from King’s College London
We are looking for healthy donors aged 18-40 or 55+ that are travelling abroad and require the yellow fever vaccine, and who are willing to donate 4 blood samples over a period of one month prior to travel. This research is to help us to investigate how the immune response changes with age.
We know that the immune response to vaccines is diminished as we get older. We are investigating the B cell response to yellow fever vaccination with age and require both older and younger volunteers for comparison. We would like healthy volunteers between the ages of 18 and 40 or those over 55 that are travelling abroad and require the yellow fever vaccine who are willing to give a small amount of blood and receive the vaccine. Three further blood samples would be required, one 7 days later, one 14 days later and one 28 days later. The vaccine is being administered free of charge to those that are participating in the study.
