Dr. Derval Igoe:

The estimate we have applies before the vaccination programme starts. It is the number we anticipate will present. Once the vaccination starts, we will know the number of people who actually come forward. For now, we are working on an estimate.

We have two different ways to do that. These are not perfect but they are the estimates that we have.

The second way was not to look at whether a person is either on treatment to prevent HIV or is living with HIV. The second way is just looking at the gbMSM community who have reported bacterial sexually transmitted infection in the last year.
