We consider the gravitationally induced particle production from the quantum vacuum which is defined by a free, massless and minimally coupled scalar field during the formation of a gauge cosmic string. Previous discussions of this topic estimate the power output per unit length along the string to be of the order of 1068ergs/sec/cm in the s channel. We find that this production may be completely suppressed. A similar result is also expected to hold for the number of produced photons.
