Then they'll be shut for ever because as Prof Ian Fraser says, a vaccine will never be developed. Our Governments should be going down the path of symptom control, particularly in the more vulnerable members of our community, those in nursing homes etc. Prof Borody may have the answer but our brain dead leaders won't go down that logical pathway. Morrison in particular is looking for the 'Holy Grail' a vaccine which won't happen but will in turn bite him severely on his political bum!!!!
