Functional Performance Of Stoppers To Support Multipuncture Use

In recent years, there has been an increase in the use of multi-dose vials. First, multi-dose vials can create efficiency and reduce packaging waste when vaccines are administered to large populations. For example, both the Pfizer-BioNTech and Moderna COVID-19 vaccines provide multiple doses per vial to maximize the number of people vaccinated as quickly as possible. Secondly, multi-dose vials enable dosing flexibility to a diverse group of patients with different dosages dependent on patient age/weight. This also applies to the animal health sector to accommodate the large diversity across different species, dosage differences, and use of various needle gauge sizes.

In this piece, review concerns with using multi-dose vials, compendial changes: USP <381> vs USP<382>, and how to reduce the risk of occurrence of fragmentation.
