We want to bring back Dr. Ashton now, joining us once again from Boston, still taking your questions, Dr. Ashton, let's start with this first one here, scientists were concerned about blood clots in connection with the Johnson & Johnson vaccine. Why doesn't there seem to be as much concern over the potential for similar clotting side effects with the use of oral contraceptives? Such an important question, you guys. And there should be that concern, because this is a perfect example of how we can't have tunnel vision, we can't be siloed and only look at one cause and effect, we have to look at this syndrome in terms of clotting, in terms of multiple causes, and yes, it is a classic effect with hormonal contraception, birth control pills, we see it across the board, how high is the risk?
