    Nah. Not worried about microorganisms. The way our immune system works is that it stores the “fingerprint” of pathogenic bacteria and viruses and this data is passed down to our progeny. So, we already have built in immunity to 1000 year old pathogens. In addition, vaccination has also “side loaded” many pathogen’s fingerprints.

      That… doesn’t make any sense. If what you said was true, every baby alive would magically have immunity to everything any human has faced ever and would never get sick. Kids are CONSTANTLY sick.

        It’s actually better than what OP said. We have a T cell for every antigen. Period. Even the ones that nobody has ever encountered. That’s because T cell receptors are proteins, that is, combinations of amino acids. Random combinations of T cell receptors are produced by the immune system (if it does not harm the host).

        The caveat is that it takes a while for the T cell of an unknown antigen to be activated, enough time for the sickness to appear and even become critical.
