The new policy represents a decisive step in a long-term strategy to improve injection safety by working with countries worldwide. We have already seen considerable progress,” Dr Kelley says. Between 2000 and 2010, as injection safety campaigns picked up speed, re-use of injection devices in developing countries decreased by a factor of 7. Over the same period, unnecessary injections also fell: the average number of injections per person in developing countries decreased from 3.4 to 2.9. In addition, since 1999, when WHO and its partner organizations urged developing countries to vaccinate children only using syringes that are automatically disabled after a single use, the vast majority have switched to this method.
