Jason Evans was just four-years-old when his father, Jonathan, died in 1993.
Jonathan, a haemophiliac, was infected with HIV through a treatment with contaminated blood, and passed away at just 31-years-old.
He was one of thousands of people who died after being treated with a blood clotting agent, known as Factor VIII, which contained Hepatitis C and HIV.
Around 2,400 adults and children passed away as a result of being given the tainted blood, and more than 7,500 people were treated with it.
Evidence has suggested health officials may have known of the problem five years before they stopped giving out the blood.
And following a 30-year campaign by victims and their families, will a public inquiry will begin later this month.
Jason told Metro.co.uk that it has been ‘a 20-year struggle for recognition’.
He added: ‘People are very happy than an inquiry has been announced because it’s never been done and it seemed impossible two years ago.
‘Spirits are higher than they’ve ever been.
‘People are concerned about how long it might take, but there’s no rushing through it because if you do that it will be a waste of time.
‘There’s hope this could bring about some form of closure for people.’
The public inquiry, announced in July last year, has been set up to establish how and why so many haemophiliacs and other NHS patients were treated with tainted blood throughout the 1970s and 1980s.
It will also look into allegations of a cover-up.
The first preliminary hearings are expected to be held on September 24.
‘My father died but it’s become bigger than that,’ Jason said. ‘Lots of people come to me with different problems – people who have lost parents, widows, children who have died.
‘It became a lot bigger than just my personal story pretty quickly.’
Jason, 28, from Coventry, said he didn’t ‘have much comprehension of what was going on’ when his father died, but admitted it was ‘very difficult’ for him.
He added: ‘By meeting surviving victims it’s given me a much bigger comprehension of what it was like. By doing what I’m doing now its definitely given me that understanding of what people want.
‘I’m very focused on the task at hand, I feel like I know what’s got to be done and how I get there.
‘It beggars belief how there’s never been a public inquiry into this until now.’
It has previously been revealed that Jonathan had voiced concerns the agent he was being given might be tainted.
And since his father’s death Jason has continually campaigned for ‘some form of accountability’.
‘What we’d like to see is an official account that pinpoints responsibilities and holds people accountable,’ Jason said.
‘A lot of people want a name. There should be a national memorial as well, especially as a lot of the kids would say “I just want to see my dad’s name on the wall, I just want a place where I can go and think about things”.
‘I’m hoping the pressure of a High Court judge might add a bit more weight to it than I can.’
Theresa May announced last year that an inquiry will be held.
Chaired by retired judge Sir Brian Langstaff, it will begin at Church House in central London and is expected to last two-and-a-half years.
