The real answer is very simple. Following the initial go at it, without the benefit of having the conversations around the international health regulations table, further analysis in terms of the risk involved, it was felt that this was not sufficient risk to leave it in there, so that's why it wasn't put in there.
We respect the views of the committee and the view of our minister that even though there's very small benefit, any benefit is worth including, and it does not increase the risk to public health. Therefore, quite appropriately, it's back in there.
