To access the data, requests must be made to the POPVAC A trial PI (Professor Alison Elliott). The request will be reviewed by the PI together with the POPVAC A investigator team. The request will be reviewed based on scientific value and to ensure there is no overlap with existing work. If the request is approved, before data is shared, ethics approval will need to be obtained in your host institution and a Data Transfer Agreement with the MRC/UVRI and LSHTM Uganda Research Unit must be completed.
