While our previous work has shown that replacing existing vaccines with thermostable vaccines can relieve bottlenecks in vaccine supply chains and thus increase vaccine availability, the...
Insoluble aluminum salts such as aluminum oxyhydroxide have been used for decades as adjuvants in human vaccines, and many vaccines contain aluminum salts as adjuvants. Aluminum salt-adjuvanted...
Lyophilization of vaccines is advantageous for the distribution and storage of thermally labile products, particularly in regions where cold chain management is difficult. To date, current...
The following is a DRAFT set of Preferred Product Characteristics (PPC) for a generic microarray patch (MAP) presentation) with a solid vaccine formulation of a live-attenuated measles-rubella (MR)...
OBJECTIVES:
Cold chain control is one of the most important facts to ensure the effectiveness of vaccines links, which requires specific material and human resources for management. The principal...

Technet was relaunched at the 2001 conference as Technet21. The New Delhi 2001 meeting, organized back-to-back with SIGN, welcomed a total of 107 participants including 23 participants representing...
Developed jointly by UNICEF and WHO, this brief \"MDVP\" mini-course provides all partners and staff working to support immunization with a better understanding of the 2014 revision of the Multi-Dose...
Background: Two-dimensional (2D) barcoding has the potential to enhance documentation of vaccine encounters at the point of care. However, this is currently limited to environments equipped with...
Background
Many countries, such as Niger, are considering changing their vaccine vial size presentation and may want to evaluate the subsequent impact on their supply chains, the series of steps...
The purpose of this paper is to present results of tests conducted to determine the \"warm life\" of a well known vaccine carrier, witand without simple modifications. The information presented in...
Introduction:
People who handle and regulate temperature-sensitive pharmaceutical products require the knowledge and skills to ensure those products maintain quality, integrity, safety, and...
