Ho-Chun Herbert Chang, Feng Fu
The rise of vaccine hesitancy has caused a resurgence of vaccine-preventable diseases such as measles and pertussis, alongside widespread skepticism and refusals of COVID-19 vaccin…
Nonlinear contagion dynamics on dynamical networks: exact solutions ranging from consensus times to evolutionary trajectories
Xunlong Wang, Feng Fu, Bin Wu
Understanding nonlinear social contagion dynamics on dynamical networks, such as opinion formation, is crucial for gaining new insights into consensus and polarization. Similar to…
Working with Large Language Models to Enhance Messaging Effectiveness for Vaccine Confidence
Lucinda Gullison, Feng Fu
Vaccine hesitancy and misinformation are significant barriers to achieving widespread vaccination coverage. Smaller public health departments may lack the expertise or resources to…
