Kai Tseng is studying Health Data Science at the London School of Hygiene & Tropical Medicine (LSHTM). Prior to his MSc, he implemented anti-COVID policies in Taiwan, where communication strategies were crucial in addressing vaccine hesitancy. As the Student Liaison Officer at LSHTM's Vaccine Centre, he co-hosted a world immunisation week podcast that challenged the term 'vaccine hesitancy' for overemphasising individual attitudes while overlooking broader health system structures. He is also co-leading a screening of the documentary 'Shot in the Arm', featuring a panel discussion with Professor Heidi Larson.
