Advocacy Accomplishments for the Year
As the first AVAC Fellow in Tanzania, Lilian blazed a trail successfully pushing for the transition of PrEP from demonstration to scale-up, as reflected in COP 2019. She secured a seat in the PrEP and HIV self-test technical working group, where she advocated for the amendment of The Tanzania HIV and AIDS Prevention and Control Act 2018 to pave the way for HIV self-testing and a lower age of consent for HIV testing from 18 to 15 years. Additionally, Lilian’s social media presence and her direct training of hotline operators helped introduce PrEP and self-testing to scores of uninitiated Tanzanians.

In Her Own Words
“I feel like a widely knowledgeable advocate now. There were things I never knew in terms of evidence and research-based information, and different advocacy tactics. So, this year has been a series of practical lessons to improve my knowledge base and applying different advocacy tactics.”
