As of October 2024, Vulcan has launched twice, both in 2024 and both successfully (though with a SRB issue on the second).
Before the second flight anomaly, ULA was planning 20 total launches in 2025, roughly split between Vulcan and Atlas.
A launch must be successful to count (this is ULA, after all - gotta hold them to a high standard!). A successful launch is defined as payload deployment success; it’s still a success if the payload itself (or the payload-provided dispenser) fails. All times are local pad time. If a launch lifts off before the end of 2025 but success is confirmed on January 1, it will still count.
ULA 2024 launch totals (as of 11/21/24): 2 Vulcan | 2 Atlas | 1 Delta

1,00011 Vulcan NSSL launches planned. With Dreamchaser, this implies they want 12 total, a very ambitious schedule.
