Community sensitisation will be undertaken to engage the community with the study and recruit volunteers for participation in the study. The CNRFP study team will hold local community meetings and explain the study to the potentially eligible adult volunteers. During these meetings the investigators will explain the following: the need for a vaccine; the current status of vaccine development (including the fact that this is likely to be a prolonged process); the study screening and informed consent procedure; risks of vaccination and the unproven benefits of vaccination. It will be stressed that these are experimental vaccine regimens and cannot be guaranteed to provide protection, and that it will therefore still be necessary to seek treatment for possible malaria even after vaccination and they should continue to use other protective measures such as bed nets. It will be explained that to aid identification, a photograph of the volunteer will be taken if they are eligible to be enrolled in the trial.
