Thank you, Dr. Morris, and thank you, Mr. Chair.
These questions are very important to answer. I don't think we have the answer to those right now, and they should be studied. It is very important to know the effect of the second dose on maturing the immune response in a safe and effective way. That, overall, has been the concern about changing whether there is, or when you give, a second dose.
These are important public health questions the member has raised, and I think we should address them.
