Halfway to a COVID-19 vaccine

Australia just had its worst ever day in the fight against COVID-19. Yesterday across the country, 502 new cases were confirmed, and in the past seven days there've been 2,414 new cases. So in the face of what is increasingly looking like a second wave, how's that vaccine coming along? Today on The Signal, we bring you good news, from two different places, on the race to find a vaccine. Could one be less than a year away? And if the virus mutates in the meantime, will a vaccine still work?
