It's interesting that R' Moshe Sternbuch's note only speaks about the
obligation of the father to vaccinate. Chinuch is on the father, if I'm
not mistaken. But shouldn't vaccination be sort of like m'nias hezek
and obligatory on both parents?

but pikuach nefesh which would apply to the mother also.

My guess is that these decisions are usually left to the mother, and the anti-vaxx nonsense has spread mostly among women, so he's now telling the men that it's their duty to insist on vaccinating the children even if their wives are opposed.
