Winnipeg health-care staff are offering free flu shots to the aliens, superheroes, sci-fi characters and other folks, costumed or not, attending the city's comic convention today.

The Winnipeg Regional Health Authority has set up a flu shot booth at the Central Canada Comic Con, which began Friday and runs through Sunday at the Winnipeg Convention Centre.

Flu shots will be available to Comic Con attendees during the day on Saturday.

Real Cloutier, the health authority's vice-president and chief operating officer, rolled up the sleeve of his Star Trek uniform for a flu shot on Friday afternoon.

"I think sometimes, as health-care professionals, we tend to be a little too traditional in the way we do things," he said.

"Like everything else that's changing in society, we got to go to the venues where people are at."

Celebrities taking part in this year's convention include WCW wrestler Bill Goldberg, Power Rangers star Jason David Frank, and Ron Pearlman, who is known for his roles in Sons of Anarchy, Hellboy and Pacific Rim.

Tickets are available at the convention centre.
