Six months ago, several hundred volunteers put their hands up to be human guinea pigs in the clinical trial of Oxford Universities Covid-19 vaccination.
The Oxford trial is of course at the forefront of the race to develop the vaccine.
Participants had their 182 day tests this week, which completes phase one of trial. Among them was UK based New Zealand journalist, Richard Adams.
He joined Francesca Rudkin from managed isolation in Christchurch to discuss the experience.
