Strange Professional Killstreak Vaccinator
This price has not changed since 2026-10-02 00:09 UTC. It reflects the last observed trade rather than current market value, and this page is excluded from our sitemap for that reason.
1 sold on the Steam Community Market in the 24 hours to 2026-10-29 15:59 UTC (7d ago), listed there as “Strange Professional Killstreak Vaccinator”. That is a different market from the prices above: Steam takes roughly 15% and pays out in Steam wallet funds rather than cash, so its prices sit above what an item realises elsewhere. Volume is unavailable for unusuals — Steam’s name for one leaves out the effect, so every effect shares a single listing.
