Why is neutralization not a redox reaction?

First, what is ? In chemistry, neutralization is a chemical reaction in which an acid and a base react to form a salt. Water is frequently, but not necessarily, produced as well.

But, what is redox reaction? Redox (or reduction-oxidation) reactions include all chemical reactions in which atoms have their oxidation state changed; in general, involve the transfer of electrons between species. For example:

In neutralization there is no transfer of electrons between species or atom didn't change its oxidation state.
