The WHO has just released a new 'Guidance Note' on vaccine diluents. It is designed to provide guidance on the proper handling of vaccine diluents and their use in reconstitution. The purpose is to enable vaccinators, logisticians and programme managers to understand how diluents should be used with vaccines and the proper conditions for their appropriate storage and stock management.
The Guidance Note takes into account the different requirements of new vaccines introduced since 2000, providing updated guidance on WHO’s recommendations for the safe handling of vaccine diluents and their use in reconstitution. It revises and replaces the WHO Vaccines and Biologicals Update, Volume 34, Proper handling and reconstitution of vaccines avoids programme errors, issued in December 2000, and has been designed to be used in conjunction with the WHO Policy Statement: Multi-dose Vial Policy (MDVP), published in 2014.
