The most pressing ethical question is to make sure that everything you do from a scientific standpoint is done for the ultimate good and positive issue for the people that you're caring about.

When we can get the incidence of HIV down enough to turn the trajectory of the pandemic, it will assume a momentum of its own in diminishing HIV.

There's more than one way to get to the goal that you want to get to, but once you compromise your own principles, then you're lost. You're really lost.

The discovery of HIV in 1983 and the proof that it was the cause of AIDS in 1984 were the first major scientific breakthroughs that provided a specific target for blood-screening tests and opened the doorway to the development of antiretroviral medications.

The difference between H7N9 and H5N1, is that H5N1 kills chickens very rapidly, so it is easy to identify where the infected flocks of chickens are. H7N9 doesn't make the chicken sick, so it has been difficult to pinpoint where the infected chickens are.

Even the pandemic flu of 1918 only killed one to two percent of the people who were infected.

Previous efforts to eradicate malaria failed for several reasons, including political instability and technical challenges in delivering resources, especially in certain countries in Africa.

Knowledge goes hand-in-hand with truth - something I learned with a bit of tough love from my Jesuit education first at Regis High School in New York City and then at Holy Cross College in Worcester, Mass.

Is it or is it not ethical to create an embryo, and to create a person for the purpose of getting an organ to give to someone else? Your knee-jerk reaction is 'absolutely not;' but you need the ethical analysis of that to show why and how that is something that you need to stay away from.

I think it would be over-exaggeration to think that there are millions of viruses ready to jump on us and bring us back to the 14th century. That would be looking over a ledge that isn't there.

There's always going to be the need for new medications, better medications.

Certainly the support for research in HIV/AIDS was good in the Clinton administration, good in the Bush administrations. It just was.

I think, collectively, we should be paying more attention to what is going on around us in the world among people who don't have the advantages that we have.

Bioethics is a very, very important field. As we get more and more in the arena of understanding science and getting better opportunities, the fact that you can do things with biological sciences that have an impact on a human being means you must have ethical standards.

You can't rush the science, but when the science points you in the right direction, then you can start rushing.

Inevitably, malaria parasites developed resistance to commonly used drugs, and mosquito vectors became insecticide-resistant.

When a company is fairly certain of a profit margin that is substantial, it can assume responsibility for the clinical trials to develop a blockbuster drug.

When you think in terms of public service, I heard so much about what Mother Theresa had done in her life. And I was fortunate enough to get a chance to meet her and talk to her a lot about what motivates her and what drives her. And that, to me, is a person that really is an extraordinary role model.

Whooping cough is not a mild disease. Whooping cough, before the vaccination, could make you very, very sick. First of all, there was a chance you could die from it - small chance, not a big chance. You would be coughing and coughing. It wouldn't last for a few days, like a cold.

Although it is still important to develop an HIV vaccine, we have significant tools already at our disposal that can make a major impact on the trajectory of this epidemic.

When I was a child, there were not that many vaccines. I was vaccinated for polio. I actually got measles as a child. I got pertussis, whooping cough. I remember that very well.

When you're dealing with a very sick person and you're doing something to them, an intervention, be it a procedure or a medication, safety is critical.

I consider myself a perpetual student. You seek and learn every day: from an experiment in the lab, from reading a scientific journal, from taking care of a patient. Because of this, I rarely get bored.

There has been treatment for hepatitis C, but the treatment has not been overwhelmingly effective, number 1. And number 2, it has had considerable toxicity.

You don't have to vaccinate every man, woman and child in the country if you have a couple of cases of smallpox cropping up.
