passing on immunity

[gib65]

Is it true that the mother will pass on her immunities to her child through the blood interface linking the plasenta to the womb? If this is true, do those immunities simply accumulate from generation to generation? Essentially, that would mean we should all be immune to things which our first human ancestors grew immune to within their lifetime.

 

Does this make sense?

Don't you lose some immunities over time? I think this is a short term effect in the case of the mother/child.

The mother can pass antibodies through the placenta in the bloodstream, and also in the milk post-partum. However, antibodies only persist in the bloodstream for a few weeks. Unfortunately, it does not operate as a cross-generational vaccination.
