Thank you very much for your question. Yes, we work closely with the CDC and also with other public health organizations throughout the world, such as the one in the U.K.
What I will say is that when we look at the evidence, as the U.S. CDC has also done, we look at the preponderance of evidence in terms of the types of guidance put forward. I will say that, for example, the IDSA actually, in a sense, represents the majority of the research scientists, the clinicians, the infectious disease specialists in the development of the guidance that they put out.
We acknowledge that there are other groups out there who have their own view of what the science shows them and who have developed their own guidance, but we certainly go with the majority expert opinion and review of the evidence.
