Reuse prevention syringes for reconstitution of lyophilized vaccines: Operational study and UNICEF plans for expanding introduction.

Since the 1990s, the United Nation's Children's Fund has encouraged injection safety for immunizations through bundling vaccines with appropriate amounts of supporting equipment and by supplying autodisable (AD) syringes for injections. However, poor vaccine reconstitution practices continue to be reported worldwide. By 2009, UNICEF will begin to phase out the distribution of standard disposable syringes for vaccine reconstitution and replace them with reuse prevention (RUP) syringes, with a full transition expected by the end of 2010. A field evaluation in Indonesia was conducted to identify introduction requirements, issues with healthcare worker training and acceptance, and RUP syringe performance and safety. Managers and health workers felt that RUP syringes improved injection safety and fit easily into country logistical systems. Healthcare workers felt they were intuitive to use, but recommended special training. The integration of RUP reconstitution syringes by UNICEF could increase injection safety by preventing the reuse of syringes and reducing vaccine contamination.

Determining measles-containing vaccine demand and supply: an imperative to support measles mortality reduction efforts.

Measles remains a major cause of mortality with an estimated 745,000 deaths in 2001. The timely, sustained, and uninterrupted supply of affordable vaccines is critical for global efforts to reduce measles mortality. The measles vaccine supply needs to be considered in the context of vaccine security. In 2000, the World Health Organization (WHO) and United Nations Children's Fund (UNICEF) issued a number of new recommendations for measles control that resulted in a two-fold increase in the number of measles-containing vaccine (MCV) doses administered between 2000 and 2002. Any additional increments in mass campaigns must be duly planned and have time lines so that vaccine production capacities are increased to optimal levels. The cornerstone of vaccine security efforts remains at the country level. WHO and UNICEF, with major partners, will review progress on measles mortality reduction and assess the feasibility of global measles eradication. Strong collaboration by all key stakeholders will be invaluable.
