Re #15 I watched a show about a boy who got infected with ecoli. The defence was plasma transfusion (I think) which was experimental at the time. He survived … barely. The bacteria tore through his body, made a hole in his stomach. The point is out sophisticated defence goes beyond the immune system into the knowledge, technology, science. Imagine what covid would be like without technology, governments, money, coordination. May have spread more slowly at the global level of course without technology but would be way more deadly.
