So - I've actually led Ebola outbreak response at USAID. This is bunk from Elon. They have laid off most of the experts, they're bankrupting most of the partner orgs, have withdrawn from WHO, and muzzled CDC. What's left is a fig-leaf effort to cover their asses politically.

Great to have this collaboration with Yanjia Cao Huanfa Chen to explore the vaccine access in 54 countries in the world. Vaccine desert exists in both high and low income countries.

Hope our research does make contribution to public health in a meaningful way. Thanks to my team members!
