Parishioners at Saint Clement Catholic Church in Medford and other local Catholic churches may notice something different over the next few Sundays.

The Archdiocese of Boston announced that it is allowing priests to suspend the distribution of wine during Communion as a precaution because of the recent flu outbreak, reported The Boston Globe.

Churches were also notified that parishioners could exchange a sign of peace by “bowing to nearby prisoners instead of shaking hands,” reported The Globe.

Last week, Boston Mayor Thomas Menino declared a state of health emergency because of the flu outbreak and some nearby communities have also ran out of flu vaccine.
