I have a stupid question for the scientists out there.
One of the disinformation messages out there claims that the vaccines change our DNA. That's obvious bullshit, but it got me thinking about the spanish flu, and how exposition to a virus helps immune systems learn to defend themselves, and future generations, better to similar ones. So how is this "knowledge" passed down ?
