As we are planning to start a clinical trial on another Ebola vaccine, we  tend to have a meeting with our CAB members to discuss on the other stakeholders we will involve and how to go about it considering positive or negative attitude people may have regarding  clinical trials. We conducted survey on our trial participants and their response geared towards working with other stakeholders.  We are doing this because the trial participants will be different from those who took part in the on going trial so we need to involve different stakeholders.
