and professional background, and represent relevant behavioural, pharmacological, pharmaceutical, medical, biological, or epidemiological disciplines, as well as public health administration. Experts participating in the WHO review are selected with careful attention given to the avoidance of conflicts of interest. Similar considerations shall apply to all concerned with the process.

The Expert Committee is assisted by a secretariat, in particular by the Expert Committee’s Secretary and furthermore by staff members from appropriate WHO programmes, consultants and temporary advisers, as required. The functions of the Secretary are executed by a technical officer competent in the subject concerned.
