Around the world, the race is on to develop a Covid-19 vaccine. So far, nearly 200 candidates are in the works, including dozens at the human-trial stage. The optimistic experts tell us that a vaccine could be ready this year or early next, and set for distribution by mid-to-late 2021. The pessimists suggest it could take longer. But few doubt that we will be able to produce a vaccine.

The question of concern, therefore, is not whether we’ll develop a Covid-19 vaccine or whether it will be safe and effective. The question of concern is ‘Who will get the Covid-19 vaccine--and when?’

On this episode of Open to Debate, David Moscrop talks with Dr. Alan Bernstein, president and CEO of the Canada-based global research organization CIFAR and member of Canada’s Covid-19 vaccine task force.
