Clinical Epidemiologist Nancy Baxter on Delta Spread

The video discusses the challenges posed by the Delta variant, which reduces the effectiveness of mRNA vaccines in preventing transmission. It explores the need for a third vaccine dose due to waning immunity, particularly in vulnerable populations. The concept of herd immunity is questioned, given the global disparity in vaccine access and hesitancy. Future vaccine development aims to address these issues by targeting more stable parts of the virus. The debate between COVID-Zero and non-COVID-Zero strategies is highlighted, emphasizing the difficulty in protecting unvaccinated populations. The video concludes with a discussion on vaccine mandates and the role of businesses in promoting vaccination.
