Many Americans have started to behave as if the pandemic is over, but large numbers of people remain unvaccinated. At the same time, other parts of the world are experiencing their worst COVID-19 surges yet.
On the season finale of The Dose, Sandro Galea, physician, epidemiologist, and dean of the Boston University School of Public Health, talks about what it will take to vaccinate the entire world and how we can protect ourselves from future pandemics.
He explains that while vaccines may mitigate the crisis in the short run, they cannot be a substitute for long-term investments in the social services that keep people healthy.
