Daniel Kapelus started his Masters degree in Vaccinology at Wits University in January 2020; the same year a new virus would cause upheaval in the world, throwing the scientific community into overdrive in the race to find a vaccine to stop the rising deaths. It was also a period that brought vaccine scepticism to new heights, fuelling conspiracy theories and misconceptions, and casting doubt on the rapidly-developed Covid vaccines. It could not have been a better – and more challenging – time for a young vaccinology student. Kapelus was thrust onto the frontlines of research for Covid vaccines, with real-world exposure to clinical trials, live data and lab research. In the latest episode on the Why Did I Become A Doctor podcast series, listen to Kapelus talk about his passion for vaccinology, which started when he switched from engineering studies to the sciences to pursue his dream.
