Vaundy has issued a health advisory after learning that someone who attended their February 14 Tokyo Dome concert was subsequently diagnosed with measles.

The diagnosis involves an attendee at the first night of "Vaundy DOME TOUR 2026 'SILENCE'" at Tokyo Dome. The band announced the news on their official website, expressing concern for their fans' health and safety.

Vaundy is asking anyone who attended the February 14 show to monitor their health closely through March 7. If concertgoers experience any symptoms associated with measles—including fever, rash, cough, runny nose, or red eyes—they should call a medical facility before visiting and wear a mask when seeking treatment.

Measles is a highly contagious viral infection that spreads through respiratory droplets. The incubation period typically ranges from 10-14 days, which explains why the band is monitoring the situation through early March.

This health alert comes as Vaundy continues their major dome tour, marking a significant milestone in the indie rock band's career. The group, fronted by vocalist and guitarist Koga Kaito, has gained substantial popularity in recent years with their dreamy, alternative rock sound.

The band's proactive approach to addressing this health concern demonstrates their commitment to fan safety. Concert venues and artists worldwide have become more vigilant about health communications following the pandemic, and this situation shows how quickly information can be shared to protect attendees' wellbeing.
