Thank you, Mr. Chair.
Thanks to all of the witnesses for joining us today. This is quite a panel, and I appreciate your taking time off of your schedules to answer some questions today.
I'd like to start my questions with Dr. Tam.
We continuously said that, as we learn more about this virus, our approach will evolve, and, as we vaccinate more and more people from different priority groups and locations, I think it's fair to say that our knowledge about these vaccines evolves too.
I've heard of a few cases abroad where the antibodies were found in babies whose mothers received the vaccination while they were pregnant. I think this is certainly something to give us some hope.
I'm wondering if either nationally or internationally you have seen any of these cases. Are there are any studies about these situations, and if so, can you tell us about them?
