博士. 马克·西格尔: “And there’s a lot of confusion, 但我想告诉你一件事, 至少这次 FDA 带来了他们的咨询小组. 他们可能不会对 5 到 11 岁的群体这样做. Why do I like that so much? I talked to Paul Offit, who’s a senior member of that committee, and he’s one of the top vaccinologists in the country. I talked to him yesterday. 他说, 你懂, it’s very clear that there’s a benefit over the age of 60. 我说, 为什么 65? 他说, 好, it could have been 60. So over the age of 60, you’re seeing some benefit. And there’s 22 million Americans who have been more than six months out, and half of them are over the age of 65, 顺便说说, they’re going to qualify if they got the Pfizer-BioNTech shot.
Now here’s where the confusion comes from, Trace. What does it mean that you need a booster? What does it actually mean? Because what they’re actually measuring is risks of mild infections, and does your antibody level go down? But you know what? You have a memory of having had that vaccine and that ramps up when you see the virus. So that protects you against severe illness and hospitalization. So there’s no reason to think the vaccine doesn’t work beyond six months. It’s just not quite as effective. And we want to prevent spread. That’s the other thing. So you give a booster, you decrease your risk of spread, you decrease your risk of severe illness. We don’t know how long that lasts. The Israel data is only a few weeks out. We don’t know if that boost we give you is going to last and endure. The vaccine itself will endure. But again, it can diminish over time.”
