The women are most likely extraordinary ministers of Holy Communion, in which case there is no problem.
The current liturgical law for the Latin Rite, the General Instruction for the Roman Missal (GIRM) permits laypersons to distribute Communion:
The priest may be assisted in the distribution of Communion by other priests who happen to be present. If such priests are not present and there is a very large number of communicants, the priest may call upon extraordinary ministers to assist him, i.e., duly instituted acolytes or even other faithful who have been deputed for this purpose. In case of necessity, the priest may depute suitable faithful for this single occasion (GIRM 162).
Moreover, the Code of Canon Law stipulates
When the need of the Church warrants it and ministers are lacking, lay persons [Latin: laici, which is distinguished from viri laici, that is, lay men; hence laici can be men or women], even if they are not lectors or acolytes, can also supply certain of their duties, namely, to exercise the ministry of the word, to preside offer liturgical prayers, to confer baptism, and to distribute Holy Communion, according to the prescripts of the law (Can. 230 Β§3).
Therefore, if those lay persons are properly deputed extraordinary ministers of Holy Communion, and there is an authentic need for them (e.g., to prevent the Mass from being excessively long; see Inaestimabile donum no. 10), then it is not a problem for them to distribute Communion.
Liturgical law does specify that there must be a true need for extraordinary ministers. The instruction Redemptionis Sacramentum spells out the criteria:
