Madam Speaker, I cannot say that I know what all countries have done, but this has been the course of the United Kingdom and Quebec. To use an English expression, the proof is in the pudding. Does it work? We can look at the United Kingdom's numbers and they have dropped precipitously. Occasionally, in medicine and in life, we have to take a chance. Yes, there is a chance, but in medicine it is all about balancing risks and benefits. There is practically no medical intervention that does not have a risk.
Yes, there is a risk in expanding the interval, but, as I cited, the evidence is that it seems to be safe. NACI is continuing to monitor it. Certainly there is a benefit and that is evident in the English numbers.
