The covering lemma can be used as intermediate step in the proof of the following basic form of the Vitali covering theorem.

The Vitali covering theorem is not valid in infinite-dimensional settings. The first result in this direction was given by

is assigned. Then, as in the Vitali covering lemma, a subcollection of these balls is selected in order to cover
