Thank you very much.
I would like to begin by saying that we entered into seven agreements for vaccines and will make sure that we are continuing to provide information, as we are able to, in terms of the confidentiality which we must keep under our agreements. There are a range of prices, and indeed we still have options to purchase under our vaccine contracts. Therefore, it's very difficult to provide an average at this time, although I will ask my deputy minister if he has anything to add on that point.
