Description

A quantitative dataset collected as part of an on-going HIV vaccine preparedness study “The PrEPVacc Registration Cohort”. The study was set up at sites in Masaka, Uganda; Durban, South Africa; Maputo, Mozambique; Mbeya and Dar es Salaam, Tanzania, to prepare a population of HIV negative individuals at risk of acquiring HIV for possible participation in the PrEPVacc HIV vaccine efficacy and pre-exposure prophylaxis trial. 

It contains information on demographic, HIV risk behavioural characteristics, HIV prevalence at screening and incidence during follow up, among participants.
