After finishing her term in the legislature, Vaca moved on to regional government, forming part of Beni Governor Alejandro Unzueta [es]'s administration as departmental director of education and culture and, later, secretary of human development.

[3] After spending some time as administrator of San Ignacio's 18 de Noviembre Hospital, Vaca moved to Trinidad, the departmental capital, where, from 2002 to 2005, she served as the librarian of the Technical University of Beni [es]'s biochemistry and pharmacy center.
