With respect to the question about transmission through pregnancy, as I said before, one of the things that everyone is looking for is answers to questions such as this.
I go back to the fact that science takes time. There is something called the scientific method that has been well established as a principle for natural science research since the 17th century. The fact is that we need cumulative evidence to answer any one question, and no single research finding is able to do that on its own.
I'm aware there are various types of studies purporting to show potential transmission risk in different types of settings. I think Dr. Hawkins mentioned, for example, congenital transmission. To date, there's been no conclusive, definitive evidence that those modes of transmission actually exist. Therefore, I certainly support that further research needs to be done in these areas to hopefully one day have definitive evidence one way or the other.
