Dr. Anelisa Jaca, a Specialist Scientist at Cochrane South Africa participated in the World Health Organisation (WHO) SAGE Typhoid Working Group meeting which was held at WHO Headquarters in Geneva, Switzerland from 17–20 November 2025.

The meeting focused on evaluating and updating policy guidance on typhoid conjugate booster vaccines (TCVs). During the sessions, the group reviewed the latest scientific evidence on TCV effectiveness and formulated recommendations for booster use. The Secretariat also presented key knowledge gaps related to typhoid epidemiology, vaccine efficacy, and optimal immunisation schedules. In addition, the working group identified priority research areas to strengthen future collaboration between the WHO Headquarters and Cochrane South Africa.

Dr Jaca said, “It was a great honour to be part of this high-level decision-making process, and I look forward to continued collaboration in addressing the research gaps highlighted during the meeting.”
