Jon Bon Jovi tested positive for COVID-19 on Saturday, shortly before he was scheduled to perform on stage in Miami Beach, Florida.

The 59-year-old musician is "fully vaccinated and feeling fine," a rep for the singer told PEOPLE.

Breakthrough cases — COVID-19 infections that occur in people who have been fully vaccinated against the virus — are possible and expected, as the vaccines are not 100% effective in preventing infections. Still, vaccinated people who test positive will likely be asymptomatic or experience a far milder illness than if they were not vaccinated. The majority of deaths from COVID-19 — around 98 to 99% — are in unvaccinated people.

The rocker was set to perform at an event called "Runaway With JBJ" at the Loews South Beach hotel when he returned a positive result on a rapid COVID test, local NBC affiliate WSVN reported. 

A crowd had already gathered at the venue when the star's positive test was revealed, according to the outlet which added that concertgoers were told the singer felt "great" and was going "to bed" while members of the band, who tested negative, remained at the venue for the scheduled performance.

According to the event's website, "Runaway With JBJ" is a three-day, two-night event in Miami Beach that offers "the ultimate fan experience" for supporters. The event, which runs through Sunday, was said to include an "Intimate Storyteller Performance," a Halloween costume party and a photo op.

All attendees were required to provide proof of vaccination or a negative COVID test.

Bon Jovi keyboardist Dave Bryan was diagnosed with coronavirus in March 2020. He told fans in a post on Instagram that he had been "sick for a week" but was "feeling better each day." 

"Please don't be afraid!!!" Bryan captioned his post, in part, adding, "Please help out each other. This will be over soon… with the help of every American !!😎💪❤️."

The next month, Bon Jovi announced that their self-titled tour had been completely canceled.
