UCLA Professor Christina Ramirez on China's Covid-Zero Strategy

The video discusses the challenges of containing the Delta variant, highlighting its high viral load and ease of spread. It examines China's zero COVID strategy and the difficulties it faces due to the Delta variant's dominance. The efficacy of vaccines is explored, noting that while they prevent severe illness, they are less effective at stopping transmission. The video also discusses how success should be measured in countries moving away from zero COVID strategies, emphasizing the importance of tracking hospitalizations and serious cases. Finally, it highlights the role of new treatments, like the Merck pill, in protecting vulnerable populations.
