On approach to land in LAS from vectors; and cleared for the visual my Captain had just turned final at approximately 3;800 feet and was on a stable descent to land. At about 1;150 feet our RA dinged 'traffic' which indicated about 200 feet below us. We couldn't see the traffic. At 940 feet to land (3;000 AGL); we had an RA warning go off due to a helicopter. The warning was to our right. We still couldn't see the traffic; but the warning soon turned into an announcement from our aircraft systems to 'pull up' at 940 feet on the RA. My Captain immediately decided to call for a go-around and we executed the maneuver appropriately; were radar vectored back to land; chose the left runway to allow for some additional distance; and landed safely without incident.Cause - A busy weekend post COVID time when the helicopter industry was seeing a lot more activity. This particular situation was out of our control to avoid. We don't generally have issues with helicopter traffic; and in this situation at such a busy airspace; we could not disregard the RA instructions so low to the ground and at such a critical phase of flight. Considering the busy nature or the weekend and the idea we are experiencing such high post-COVID activity in Las Vegas; perhaps we as a crew could have suggested the left runway for some extra separation; but it's never been an issue in my time flying before.
On visual approach fully configured turning final at approximately 3;700 feet; when rolled out on final an RA was enunciated and a subsequent go-around was performed. We returned to fly visual to the left runway with no further issues. Helicopter traffic operating too close to the active runway approach path. Either keep helicopter traffic further west or make the left the primary runway for south landing traffic.
Air carrier flight crew on short final to LAS reported a go-around due to a TCAS/RA Alert for a VFR helicopter.
