Covid-19 vaccine strategy needed, scientists say

Infectious disease experts say the government must develop a national vaccine strategy, and someone to lead it. It comes as fears mount that New Zealand could be at the back of the queue for a Covid-19 vaccine. It's estimated that at best, a vaccine is 12 to 18 months away, or longer, if not developed here. Add to that no human ever encountered it before December 2019, so no-one had any COVID-19 reference material, and we don't have vaccines against any coronavirus yet. Kathryn Ryan talks to the University of Queensland's Ian Frazer who worked on the HPV vaccine, University of Otago infectious disease specialist Professor David Murdoch, Wellington's Malaghan Institute director, Graham Le Gros and Dr George Laking from Doctors for Healthy Trade about their concerns.
