The family of a Stowmarket engineer said "sharing the horrific ordeal" the 27-year-old went through must be done in order to "highlight the litany of errors" that cost him his life.
A report released into his death on Tuesday revealed system errors led to Jack Last receiving the AstraZeneca Covid-19 vaccine before he should have.
In December 2022, a coroner concluded the 27-year-old died as a result of the Oxford AstraZeneca Covid-19 jab he was administered with.
A family statement released in the report said: "This statement isn't something any family would expect to make. However, sharing the horrific ordeal that Jack was put through is something that must be done to highlight the litany of errors that have cost Jack his life.
"Jack was a happy, healthy, carefree 27-year-old. He had thick brown hair, big brown smiling eyes and a kind smile.
"He loved his job, working as an engineer for Caterpillar machinery and was also putting his skills to use working on an old car in his spare time. He loved seeing his family, his friends, keeping fit and exploring.
"He was witty, entertaining and always kind to everyone he met. Jack had previously taken a six month career break to work with machinery in Antarctica for the British Antarctic Survey, he completed several Tough Mudder challenges and could often be seen at his local park run. For Jack, life was worth living, and he made the most of every moment.
"Before Jack had his Oxford AstraZeneca COVID-19 injection, he hadn’t had a single day sick from work.
"He was very rarely unwell. Then suddenly he was not fine. It all happened so quickly, it still struggles to hit home at times that we are never going to see him again.
"Conversely, the time from him being invited for his Oxford Astrazeneca COVID-19 injection, to dying, somehow also seemed to last forever, waiting to hear that actually, he would be OK. But of course he was not OK and none of this will ever be OK."
The family said it was "heartbreaking" to learn that he was contacted to receive the due to family records stating they had a disease which they no longer had.
Jack had also previously requested Mendlesham Health Centre, his GP practice, to change a telephone number that remained on his records.
The statement continues: "Shortly after receiving his jab, the reports of Oxford AstraZeneca injections causing deaths were starting to gain attention, but by this time it was too late, Jack had already had the injection.
"We hope a lesson in accurate medical data keeping will be learnt from this, particularly if in national emergencies medical data is shared with other agencies.
"The report details the many horrendous and ultimately catastrophic errors from the moment Jack arrived at West Suffolk Hospital. It appears that at every turn since he checked in something went wrong, and Jack just couldn’t catch a break.
"It is also profoundly sad that in Jack’s last moments, he had to be by himself for the most part due to implemented COVID-19 restrictions (1 family member could see Jack for 1 hour a day), and staff were at times unkind to him.
"While texting friends during his long wait at West Suffolk Hospital, he was asked numerous times by the receptionist “who even sent you here?” (it was, quite rightly, the 111 service). He was told “it is a coincidence” and said to his friend he was worried “I think I’ve been left”.
"Jack spent his whole life being kind, and it is absolutely soul crushing to think that when Jack needed kindness the most, at times this was not found.
"We believe part of the reason Jack was not taken seriously at the hospital to begin with was because the “safe and effective” mantra had been repeated so much to the point of it being gospel, that anything that went against this seemed offensive.
"As though you were somehow wishing COVID-19 on others or you were being deliberately difficult.
"The symptoms of VITT should have been picked up, and Jack referred to a specialist with life threatening urgency, but instead he was treated as though he was some kind of trouble maker for reacting to the Oxford AstraZeneca COVID-19 jab.
"We hope that even one part of this report does not happen to someone else. It’s unbearable to think that due to these events, Jack has lost his right to a full and happy life at such a young age. We now have to live with the knowledge of these horrors and without Jack."
