The rapid spread of the Omicron variant of Covid-19 is leading to record infection levels in several countries, and vaccination is a key part of the fight against the pandemic. Host James Reynolds brings together vaccination workers in South Africa, Australia, the United States and the UK to share what’s it like to be part of the global effort to vaccinate.

We also hear from two people in the US and the UK who turned down a vaccination. After almost dying, they regret their decisions. “I had no idea what was going into me when they [health workers] were saving my life - the same as I don’t know what’s in the vaccine,” says Jade in the UK. “It’s silly isn’t it? You kind of overthink one thing but not the other.”
