Behold the ultimate mic drop for anyone claiming they're "vaccine educated" after watching three YouTube videos! This quiz is basically immunology's version of "tell me you slept through biology without telling me you slept through biology." The questions cover complex immunological concepts like lymphocyte identification, antibody chain responses (IgM is first, by the way), toll-like receptors, cytokine functions, and T-cell maturation pathways. Meanwhile, the average anti-vaxxer's "research" consists of Facebook posts from that one relative who thinks essential oils cure everything. The savage punchline at the bottom perfectly captures the disconnect between actual scientific research and "I read something on a blog once." Next time someone says they've "done their research" on vaccines, maybe hand them this pop quiz and watch the panic set in faster than an immune response to a foreign antigen!
