When Leo Harvey went to get his first vaccine, it took him a 30-minute round trip.
But to get his booster shot, he faces a four-hour long journey using two buses and a train - and all because he relies on a wheelchair.
Mr Harvey, from Tunbridge Wells, said the online booking system has been "useless", as it can't guarantee a facility has suitable accessibility for his needs.
To get to the Eldred Drive pharmacy in Orpington where he can get a booster shot appointment, Mr Harvey will need to travel for two hours in each direction.
Mr Harvey said: "We're supposed to be vulnerable people. So you would think they would make it easy for vulnerable people to access the system - but they don't."
He added: "It's ridiculous. Maybe in 1950 it was acceptable to say there's nothing we can do, but you know, we can't all be like Tanni Grey-Thompson and be an Olympic athlete.
"Lots of disabled people will go to work now and live full lives and do everyday normal stuff. All I wanted to do was an everyday 'normal thing' and go and get my booster jab. It can't be rocket science, I can't believe it can be so hard."
Mr Harvey said he doesn't need help getting there - but he just wants to get his jab closer to home.
In response, the NHS Kent and Medway CCG's Chief Nurse Paula Wilkins, told ITV Meridian she was "very sorry to hear about Leo's difficulties finding a vaccination clinic that meets their access needs."
She said: "If there aren't any appropriate slots available when you first check, we would encourage people to try again a few days later."
She added they are "working with partners across Kent to provide transport support for those who may have difficulties getting to a vaccination centre."
