Vaccines and hysteresis with Xingru Chen

Despite the resurgence of vaccine-preventable diseases and public awareness of vaccine importance, why is it so challenging to boost population vaccination coverage to desired levels especially in the wake of declining vaccine uptake? A new study from Dartmouth College shows that past problems with vaccines can cause a phenomenon known as hysteresis, creating a negative history that stiffens public resolve against vaccination. Joining me today to talk about this phenomena is lead author, Xingru Chen. Ms. Chen is with the Department of Mathematics at Dartmouth.
