 I think this could be really groundbreaking. We've seen worries about increases in HIV rates among women and adolescent girls in the past years. This is a huge community of concern for PEPFAR, among others. And so if you have a tool that is discreet, that people want to use, and that is almost 100% effective in preventing transmission, then you could see significant declines in new HIV infections. And that would go a long way.
