Immunization injections are also a potential hazard. A sufficient supply of needles, syringes, sterilization equipment and disposal boxes is as important as an adequate supply of vaccines. Injections are safe when the vaccine or medication is properly administered with sterile equipment that is disposed of safely. Unsafe injections practices can result in many complications. In most countries, infectious diseases are the most common problems.
Incorrect disposal can also lead to accidental needle sticks.
To ensure that injection do not transmit infectious diseases, a sterile needle and a sterile syringe must be used for each injection. The used needle and syringe must then be disposed of properly,or re-sterilized, depending on the type of equipment. Although these conditions seem very simple, unsafe injections continue to be given throughout the world, often by health care workers who have been properly trained. This document describes the steps which are needed to ensure safe injection practices. While the document is intended primarily for immunization programme managers, the strategies are applicable to all sectors of the health service.
