Politics with Michelle Grattan: Nobel Laureate Professor Peter Doherty on the coronavirus crisis and the timeline for a vaccine

Written by: Michelle Grattan, Professorial Fellow, University of Canberra

The coronavirus SARS-CoV-2, which causes the disease COVID-19, has infected nearly half a million people and taken the lives of more than 21,200.

No person in Australia is more qualified to speak on the science of this global pandemic than Professor Peter Doherty. Professor Doherty was awarded the Nobel prize for medicine in 1996 for his work studying the immune system. The Doherty Institute, now at the forefront of Australian research on the coronavirus, bears his name.

In this episode of Politics with Michelle Grattan, Professor Doherty discusses the particulars of the pandemic - including how controlling this pandemic differs from that of other illnesses:

“It’s a problem of dealing with a respiratory infection,” he said.

“It’s different from, say, AIDS. We can all modify the way we behave in the sexual sense, but we can’t decide not to breathe. And so it’s very important that we keep that social distancing right at the front of our mind. In fact, one of the best pieces of advice I’ve seen is, think [as if] you’ve already got it and you don’t want to transmit it to anybody else. And if you think like that, you’ll protect yourself. ”

Scientists from The Doherty Institute were the first to successfully grow the 2019 novel coronavirus (COVID-19) from a patient sample. According to Professor Doherty, a COVID-19 vaccine could be available within 12 to 18 months.

“There are a few new concerns from experiments with the earlier SARS and MERS viruses in lab animals…that some vaccine formulations could give you what we call a bit of immunopathology, and even make the disease worse,” he said.

“So we have to be careful with the vaccine. But there’s also good evidence that a safe SARS vaccine worked well in monkeys. Targeting the same protein, the first COVID-19 vaccine product from the University of Queensland has already gone into lab animals.”
