    An important note is the fact that vaccines do not cause Autism Spectrum Disorder. The doctor who found the ‘link’ between these two factors has lost his licence as the study was poorly done and inaccurate.

    It'd be interesting to learn more about Dr. Quarraisha Abdool Karim. A woman of color doctor in apartheid South Africa dealing with a disease that was relegated to a "gay disease" in America. I don't know how it was treated in South Africa, but i bet it wasn't great. I love women-in-STEM stories, I'm going to look her up.

    Really wish this video was available at the start of the mRNA conspiracy theories, but sharing it now with the uneducated will still help.

    3:49 If a virus cannot live on its own without other life, what would it begin with? 🤨 The natural world is so complicated! Anyway, thank you for the great lecture! 👍

    While I'm not a STEM student, I took AP Biology during 2020-21 which was right in the beginning of the pandemic. This video feels like a flashback to that, in a good way

    I’m sure viruses inspired the movie Prometheus. The discussion about whether viruses are alive or not has always been interesting to me.
