Michael Nehls, MD, PhD: "If you want [people] to think 'peace'... [you need] new nerve cells in the hippocampus... [but] spike proteins undermine [that] production... So a spike protein injection by mRNA... undermines the ability to think 'peace.'" This clip of Nehls, MD, PhD (@NehlsMD), a molecular geneticist, immunologist, author, and educator, is taken from an interview with Del Bigtree (@delbigtree) posted to Nehls' eponymous YouTube channel on March 4, 2026.

"For those of us who've noticed that people who've taken the mRNA vax and boosters seem different psychologically, we're not imagining that." "No. It's what's really happening." Michael Nehls, MD, PhD (@NehlsMD), a molecular geneticist, immunologist, author, and educator, describes for Tucker Carlson (@TuckerCarlson) how the COVID injections affect a recipient's hippocampus—that is, the part of the brain that's involved in many cognitive functions, including memory and learning. "I saw that actually...in people I know...when I saw them at parties, we could talk about everything that's trivial," Nehls says. "But as soon as you start to talk about something more difficult that was before 2020, you realize they don't want to put their brain into in a working mode. They just avoided these topics and these very people who are not interested in really thinking were the ones who actually took the shots very quickly. Partial transcription of clip: Carlson: "For those of us who've noticed that people who've taken the mRNA vax and boosters seem different psychologically, we're not imagining that." Nehls: "No. That's what's really happening. You see, people who are not who have not a high production of these cells in the hippocampus, they act normally during the day. In a normal situation, they do whatever humans do and you don't realize it. I saw that actually...in people I know that, when I saw them at parties, we could talk about everything which is trivial. But as soon as you start to talk about something more difficult that was before 2020, you realize they don't want to put their brain into in a working mode. They just avoided these topics and these very people who are not interested in really thinking were the ones who actually took the shots very quickly. Because you have to see the mental immune system, as I already counted off, curiosity is lacking. "The other side of the coin of curiosity is psychological resilience, because being curious, meaning you enter a new space, new thoughts and everything that's new is per se potentially dangerous. So you have to have a high psychological resilience to enter this new space. So if both the sound curiosity and psychological resilience, then you accept everything. And particularly, if something comes with a lot of fear, you know, oh, you could die, your family could die, everything is very, very dangerous, then you fall back to, I would say, cortical reflexes like something that is inborn in us, behavior that's inborn. And one behavior that's inborn, of course, in humans is and that's natural...if there's a danger, you go into the room. You don't try to be isolated. You go, you follow the group. And if people tell you the group is going to take this vaccine, then everybody runs and I will have it too. You don't think, you just follow the crowd."
