Rotavirus does not cause all diarrhea, but it causes a lot of it. Instead of a single vaccine dose, however, harried nurses may have to give several, as diarrhoea makes it difficult for a child to retain anything.

I was making comebacks every single year. That makes it difficult mentally. It causes a lot of stress.

We feel this is a very promising concept for a vaccine for traveler's diarrhea.

Diarrhea, 90 percent of which is caused by food and water contaminated by excrement, kills a child every fifteen seconds. That's more than AIDS, malaria, or measles, combined. Human feces are an impressive weapon of mass destruction.

It is still just unbelievable to us that diarrhea is one of the leading causes of child deaths in the world.

The dose makes the poison.
