A Quote by Peter C. Doherty

This year, 1996, has been designated the 'Year of the Vaccine,' commemorating the 200th anniversary of Edward Jenner's vaccination of James Phipps with cowpox virus and subsequent challenge with smallpox virus. Insight into the nature of viruses, and how viruses interact with mammalian cells, has evolved since the turn of the century.
My general theory since 1971 has been that the word is literally a virus, and that it has not been recognized as such because it has achieved a state of relatively stable symbiosis with its human host; that is to say, the word virus (the other Half) has established itself so firmly as an accepted part of the human organism that it can now sneer at gangster viruses like smallpox and turn them in to the Pasteur Institute.
We have Borna virus genes. We're part Borna virus, which is weird, but apparently our cells and our genomes in a weird way might actually be grabbing these viruses, grabbing genetic material from the viruses that are infecting it and pulling them into their own genome.
The reason that viruses are so hard to fight, the reason for example we need a flu virus every year is that they evolve very fast.
With the absence of a flu vaccination last year, I did not take a flu shot; but there is still some immunity that carries over from year to year; but about every 30 years, there is a major change in the genetics of the flu virus.
Over millions of years the viruses in our genome mutate more and more so the look less and less and less recognizable as viruses and so if there was a virus that infected our pre mammal ancestors like 250 million years ago, which it probably did, we can't see it because it just looks totally random.
I would not go so far as to say that vaccination has never saved a person from smallpox. It is a matter of record that thousands of the victims of this superstitious rite have been saved from smallpox by the immunizing potency of death. But it is a fact that the official statistics of England and Wales show unmistakably that, while vaccination has killed ten times more people than smallpox, there has been a decrease in smallpox concomitant with the decrease in vaccination. . . It might be appropriately asked, in the words of the Vaccination Inquirer
During the last considerable epidemic at the turn of the century, I was a member of the Health Committee of London Borough Council, and I learned how the credit of vaccination is kept up statistically by diagnosing all the revaccinated cases (of smallpox) as pustular eczema, varioloid or what not---except smallpox.
One of the big challenges now is to figure out just how many viruses there really are in the human genome. So far the estimate is 8.3% of our genome is virus, but it actually could be a lot higher.
Surveying the way viruses have been discovered in the past, I came to the conclusion that I could use my technology that I developed as a graduate student - DNA microarray technology - to create a chip that would simultaneously screen for all viruses ever discovered, and furthermore have the built-in capability of discovering new viruses.
I do think the Roman Catholic religion is a disease of the mind which has a particular epidemiology similar to that of a virus... Religion is a terrific meme. That's right. But that doesn't make it true and I care about what's true. Smallpox virus is a terrific virus. It does its job magnificently well. That doesn't mean that it's a good thing. It doesn't mean that I don't want to see it stamped out.
It is fashionable to wax apocalyptic about the threat to humanity posed by the AIDS virus, "mad cow" disease, and many others, but I think a case can be made that faith is one of the world's great evils, comparable to the smallpox virus but harder to eradicate.
I'm tired of being behind this virus. We've been behind this virus from day one. We underestimated this virus. It's more powerful, it's more dangerous than we expected.
We may be sucking in all sorts of viruses and we really don't know the full range of them. Maybe we've got flu virus inside of us. That's a possibility. Maybe we're part flu.
Viruses have to live somewhere. They can only replicate in living creatures. So, when the Ebola virus disappears between outbreaks, it has to be living in some reservoir host, presumably some species of animal.
The nature of a protective immune response to HIV is still unclear. Because in a very, very unique manner, unlike virtually any other microbe with which we're familiar, the HIV virus has evolved in a way that the immune system finds it very difficult, if not impossible, to deal with the virus.
DNA is the master blueprint for life and constitutes the genetic material in all free-living organisms and most viruses. RNA is the genetic material of certain viruses, but it is also found in all living cells, where it plays an important role in certain processes such as the making of proteins.
