Jacksonville, Fla. – Airlines and others in the travel industry are throwing support behind vaccine passports hoping to boost pandemic-depressed travel. “Any program that differentiates between people that are vaccinated versus people that are not is only as fair as vaccine distribution itself. “The World Health Organization did release some guidance, but they can’t actually mandate compliance especially for private companies,” Asi said. It could begin a vaccine passport program by May, but Asi said the state might not need one by then. “And my hope is that we’ll have reached herd immunity by that time so these passports will be obsolete anyway.”
