The year’s final Kopi Time podcast features a deep dive into the science of vaccines. Associate Professor Jenny Low, a senior consultant with the Department of Infectious Diseases in Singapore General Hospital, breaks down everything we need to know with respect to ongoing vaccine developments. Want to know the difference between the vaccines being developed by Moderna, AstraZeneca, and Pfizer? How are they being developed so much faster than ever before? How is effectiveness calculated? Can a vaccinated person be infectious? How long are we likely to remain immune after vaccination? How is Singapore’s efforts to develop a vaccine going? All this and more from Dr. Low, who is at the forefront of the fight to end this once-in-a-century pandemic.
