“A number of immunisation programmes are funded and announced by the government and international bodies, but little thought goes into the injecting or delivery mechanism.”

“I grew up in England, went to a nice public school, then didn't want to go to university, so I thought I would wander around. I did a season skiing, a bit of sailing, typical spoilt brat stuff. I ended up in the Caribbean. I was having a blast.”

“Twenty-two million cases of hepatitis B are spread every year because of the reuse of syringes. The WHO says one in two injections given is unsafe.”

“I read a newspaper article in May 1984 which predicted that syringes would one day be a major cause of the transmission of HIV. It was what I had been waiting for - a project that had a lot of the things that I liked: problem-solving, product design, campaigning, and being a bit of a big mouth pain-in-the-bum.”

“The Tanzanian government recognised there is a problem: that they don't have enough sterile syringes, that they are being reused probably four or five times each, and that this reuse is a massive contributor to their burden of healthcare.”
