even before the coronavirus pandemic started, the Rainbow Nation was battling a tide of anti-vaccine misinformation online. And one study found that although there is a relatively small group of South African anti-vaccine activists, they are being bolstered by a wave of material coming from abroad.

We meet a pharmacist who has been tracking the alarming reach of that small group of hardcore anti-vaccinators for the last five years. And we hear how the country’s class system contributes to a big divide in willingness to take vaccines.

Plus we hear from the activists staging a fightback against the Covid-19 “infodemic”. Sarah is a mole in a number of anti-vax chat app groups and runs a pro-vaccine Facebook page aimed at countering their disinformation. But can she convince someone with questions about vaccines to actually get one?
