McEntee said Aaron’s death had ignited a “passion” in him that no other family should have go through what Aaron’s had.

“He was capable, kind – the gentlest, warmest person you could meet,” he said. “And he’d want nobody else to suffer the same fate.”

He is aiming to raise £2,000 for the charity Meningitis Now.

“Ultimately, every step is in Aaron’s name,” said McEntee. “It’s to raise awareness, to raise funds, all of that. But it’s all got to be for Aaron.

“It’s almost as if it’s him raising the awareness, and I think that’s poignant.”

But McEntee’s challenge is also a celebration of Aaron and his legacy.

“The Mills family campaigned so hard,” he explained. “Aaron’s story was so influential in the government’s decision to roll out [the vaccine].

“So we should be celebrating that, and celebrating Aaron.”
