My fascination is broadly with biology and the fact that our increased understanding of biology allows for breakthroughs in a broad set of diseases.
The world has been very careful to pick very few diseases for eradication, because it is very tough.
AIDS is a disease that is hard to talk about. The ideal thing would be to have a 100 percent effective AIDS vaccine.
It's really a tragedy that the world has done so little to stop this disease that kills 2000 African children every day.
The belief that the world is getting worse, that we can't solve extreme poverty and disease, isn't just mistaken. It is harmful.
It is hard to overstate how valuable it is to have all the incredible tools that are used for human disease to study plants.
I don't think there is any philosophy that suggests having polio is a good thing.
Nobody spends any money on smallpox unless they worry about a bio-terrorist recreating it.
Polio's pretty special because once you get an eradication, you no longer have to spend money on it; it's just there as a gift for the rest of time.
Ninety percent of the cases of polio are in security-vulnerable areas.
My experience of malaria was just taking anti-malarials, which give you strange dreams, because I don't want to get malaria.
In low-income countries, the main problems you have is infectious diseases.
The AIDS is a disease that is hard to talk about.
This is a very tough disease. It is going to take all of us -- private sector, the pharmaceutical companies, philanthropy and governments in countries that have the disease -- to participate as well.
