Aircraft
Climbing out; at about FL260; I Pilot Flying (PF) noted the EICAS became de-cluttered. I pointed it out to the Captain; and we found ENG 1 LP VIB to be at 4.0; which is in the yellow caution range.We leveled at FL280 and the Captain ran the QRH while I remained in control of the airplane and took over the radios. As instructed by the QRH; we were able to get the ENG 1 Low Pressure (LP) Vibration stabilized at about 78% N1. At this power setting; we were still able to maintain altitude and airspeed; so we discussed the possibility of continuing to [destination]; checking drift down; fuel plans; and other precautionary items.During this time; the Captain also contacted dispatch; Maintenance; and Ops; and included them in the loop. He had them rerun the flight plan at FL280 and our current speed. They concurred that we could continue to [destination].No further issues were noted.Upon arrival; we were met by Maintenance.  They determined that we needed to do an engine run-up check with them. The Captain and I coordinated with OPS and ATC; performed the run-up with MX; which was satisfactory. Maintenance signed off the writeup; '...could not duplicate...' and we loaded up passengers to continue our next leg.
EMB-175 First Officer reported they received an EICAS message ENG 1 LP VIB. Flight continued to destination after running the QRH.
