Thank you, Chair, and thank you to all of the witnesses for being here and also for their patience this evening as we get towards the end of this really interesting testimony.
Dr. Barrett, I'm going to stay with you for a while. Towards the end of your five-minute talk, you had started to touch on the need for post-market vaccine studies to better understand immunity to pandemic pathogens. Again, I'm thinking of how we are looking forward, how we are preparing for the next one.
I wonder if you can elaborate somewhat on that issue of what we need in terms of federal support and how this might relate to this bill.
