Does Vaccine Power Really Wane?

Does Vaccine Power Really Wane?

September 2021

In everyday life, participants aren’t randomized to account for different ages, behaviors, etc. We need careful modelling and thorough data “to de-convolve all these things.”

About Us

To understand health and disease today, we need new thinking and novel science —the kind  we create when multiple disciplines work together from the ground up. That is why this department has put forward a bold vision in population-health science: a single academic home for biostatistics, epidemiology and informatics.
