Episode notes

In countries across africa, about one point two % of people have got in a single dose. In lower middle income countries, it's less than 15% of the population has been vaccinated. Those numbers are really drastically divergent. The public health argument is that by having covid continued to be able to surge in places without vaccines, it really does put the entire world at risk. It's very much taught us that you can't just put up a travel band and expect that variants aren't going to spread everywhere.

Several wealthy nations have announced plans to give third vaccine doses in a bid to help increase the protection of their most vulnerable citizens - but the science is not clear on whether this strategy will be effective or indeed necessary. Meanwhile with limited vaccine supplies - billions around the world still have no access to vaccines at all. In this episode of Coronapod we discuss the science of boosters, the stark reality of vaccine disparity and what this means for the future of the pandemic.
