Originally the Diamondstick was designed to substitute needles in order to simplify vaccination in countries with poor health conditions, like Mozambique..The idea was that needle-free xposure to medicine by dermabrasion could increase access and acceptance of mass vaccinations and treatments.
For populations with low education or reluctancy towards scholar medicine, a “skin abrasion device”, especially one that is also used for aesthetic purposes, might appear less harmful than an injection needle.
Simple application and without the need of health care professionals, dermabrasion based mass vaccinations might be the needed breakthrough to access more people, also in rural areas.
