Thirty seconds, okay, thank you.
It varies from vaccine to vaccine and from time in history to time in history. I'm glad you raised the papillomavirus vaccine, because there's the chance of wiping out--virtually wiping out--cervical cancer using this vaccine and screening. That's a women's health issue and it needs to be addressed.
I think we need to have a set amount of money that can be used and perhaps reserved from year to year so that as new vaccines come along, if we don't spend it one year, it will be available for the next year. For example, there's a rotavirus vaccine against diarrhea, a childhood diarrhea that keeps kids out of day care and keeps parents out of work, that I think is going to be an important one for us to consider implementing across the country as well.
