Dr. Jacobs, I'll go to you and just ask you if you have any opinion to offer. I know that, in following you on social media, you're very pro-vaccine. Are there any thoughts on Dr. Kalyan's position as it relates to omicron? It's a good opportunity to have a back-and-forth.
Then if Dr. Kalyan wants to weigh in, I'd be glad for her to have the opportunity to do so.
