I can see no hope at present of such a vaccine being produced... I have adopted a frankly defeatist attitude towards the problem of poliomyelitis and I hope that future developments will prove me wrong... No means of controlling poliomyelitis is at present visible. (Frank Macfarlane Burnet)
I can see no practical application of molecular biology to human affairs... DNA is a tangled mass of linear molecules in which the informational content is quite inaccessible. View quote
Frank Macfarlane Burnet
One of the minor regrets, not really a big regret, is that I've never published a paper with Mac Burnet. I've published 500 papers, not a single one has Burnet as a co-author. He did not believe in putting his name on a paper if he hadn't done at least one third of the work himself. A sort of an honest unselfish approach, when it comes time to reap the glory you do it without having someone grabbing it instead of you. View quote
