"DAVID can win over Goliath. When business is done the right way, everybody wins," said entrepreneur and founder of Biozeen medical company.
And the story of this charismatic businessman and philanthropist is indeed an extraordinary tale of one person taking on the mighty cartels of the drug companies.
After seeing one of his teachers become upset when talking about the high rate of child mortality from preventable diseases, Vibin decided to change the way that vaccines are manufactured and produced.
"Global life expectancy is at its highest ever, and yet despite that, 6.6 million children die every year from diseases which can be prevented by vaccine," he said.
So in 2011, engineering graduate Vibin set up Biozeen.
"Its mission was to enable companies to manufacture vaccines that are affordable by using a completely new approach of open-source technology."
NAME: Peter Morrissey
SOCIAL entrepreneur Peter Morrissey set up a project with friends in a bid to solve two major issues affecting society - loneliness and the student accommodation crisis.
The former UCD student co-founded Generation Accommodation, which has already matched 22 dependable students and elderly people living alone near the university, who had a room to let. The student rents a room for about 40pc less than average. The not-for-profit, which has another 60 potential matches on its book, plans to double its numbers by the New Year, be nationwide by next September and European-wide in September 2015.
"If they match on paper we get them to meet a couple of times and build a rapport with each other," he said. "We've had no complaints so far."
The company was created last year with Enactus Ireland and, after winning the national award, will represent Ireland at 2014 Enactus World Cup Final in Beijing next week.
NAME: Noam Shuster
NOAM Shuster has had an unusual upbringing but she knows no other. The peace activist grew up in Oasis of Peace, an intentional community jointly established by Jewish and Palestinian Arab citizens of Israel.
Located midway between Jerusalem and Tel Aviv, the village - Waah-at i-sal-aam in Arabic and Ne-vé shal-om in Hebrew - houses 80 families equally divided between usually warring peoples.
"It's very different from the reality outside," she said. "I was exposed to both narratives living together, I really feel like I carry on my shoulders the kind of example and the alternative.
"My way of life demonstrates what I think the solution is. It's not just talking, it's being completely aware of both sides and being completely aware of the different historical narratives."
Ms Shuster now works with Interpeace, an international organisation helping war-torn societies to build lasting peace, and looks at Northern Ireland as a success story.
NAME: Saba Nafees
CONNECTING First World resources that are available with Third World countries which need them is top of the agenda for post-graduate maths students Saba Nafees.
Designing solar-powered educational tools and creating a product that will make cardboard homes waterproof in disaster zones are just two of the projects she's involved in with mentors at Texas Tech University.
"It has some really great valuable implications for helping developing nations," said the Pakistani-born student.
But the young woman has even bigger ambitions and wants to continue her studies in mathematical biology and focus on genetic and biological diseases. The 22-year-old said the One Young World summit is a phenomenal event.
"Just the idea of bring together world leaders from across the globe and putting them in one place and making them talk to each other and figure out what the problems are is a great idea."
YOUNG people from all over the world have jetted in to Dublin for a four-day summit.
The aspiring leaders of tomorrow have travelled from 190 countries to hear from experts in the fields of business, politics, arts and science, including former President Mary Robinson, former UN secretary-general Kofi Annan, One Young World founder and CEO of Unilever Paul Polman and tennis legend Boris Becker.
But each young person also has their own story to tell and has been sponsored by an organisation to attend One Young World and learn more from each other.
