Excuse me, Mr. Van Exan, we're running out of time. Thank you for your comments.
We have about 30 seconds or so left, and I'm wondering if I can ask a question. Okay.
I don't know if you can answer this, Dr. Griffiths, or if I need to ask Public Health. For people who have compromised immune systems because they have HIV, cancer, bone marrow transplants, or rheumatoid arthritis, what kind of vaccine is recommended? Is it the one with the adjuvant in it? What is the recommended dose for someone like that?
