We had already been cleared for the ILS Runway 8 Approach and we were following the localizer and glideslope using the autopilot. At approximately 2;400 feet on glideslope; the Tower Controller advised us that we had traffic at our 1 o'clock position at about a mile. Neither the Pilot Flying nor I saw the other aircraft; and as Pilot Monitoring; I advised Tower as such. Within a few seconds; TCAS gave us an RA; stating 'Monitor Vertical Speed' and displayed symbol accordingly on our PFD screens. The Pilot Flying took manual control and leveled our VSI following the RA guidance. As we monitored the TCAS symbol for the traffic we noted that it was showing 600 feet below our altitude and continuing from ahead and right of our path toward our intended course. The Pilot Flying then adjusted course slightly left of the localizer course line. Soon after this adjustment; the TCAS advised that the traffic conflict was resolved. The Pilot Flying then recorrected back to localizer course and glideslope which was easily accomplished being that we were no more than one dot left of localizer and one dot above glideslope. As Pilot Monitoring; I told Tower that the conflict was resolved; but that we had gotten the RA and followed the guidance; and were continuing the approach. The rest of the approach went without further event.
An air carrier First Officer on an ILS final approach reported responding to a RA and taking evasive action to avoid an unidentified converging VFR aircraft.
