To ensure that solar direct drive (SDD) appliances can keep vaccines at acceptable temperatures continuously, the installed photovoltaic array often produces excess power that is not used by the primary cooling load and this excess power generally goes unutilized. If this power is to be used, the p...

A new PQS freeze protected vaccine carrier has been approved. The incorporation of this new carrier would solve a serious problem but at a considerable cost. PATH estimates that 2 million carriers would have to be replaced. Several years ago we had been working on a freeze protection method which i...

PATH’s Freeze-Safe innovation sets a new benchmark, helping protect vaccine potency, reducing health worker burden, and providing cost savings to health systems Seattle, February 7, 2018—This week, the first commercially available freeze-free vaccine carrier will begin introductory field trials in ...

Electronic immunization registries (EIRs) and other immunization information systems can be powerful tools, but in order to achieve their long-term sustainability, countries and governments must understand the financial investment to develop, implement, and sustain such tools as the BID Initiative's...

Hi All, PATH Senegal Office had proceeded last year a field evaluation of Sure Chill’s long-term passive device for the use of cold storage of vaccines in Senegal and provides important feedback in terms of thermal performance, end-user inputs, and perceptions at the Ministry of Health of the poten...

Happy new year all, We are happy to announce that the latest version of the Total Cost of Ownership tool for cold chain equipment (v1.3) is now available to download and use. The latest version has a few minor changes to the presentation of data as well as the latest PQS pre-qualified equipment as ...

Hello all, Microarray patches (MAPs) are under development for delivering vaccine into the skin. The technology has exciting potential for application to immunization programs. PATH is looking for input from experts in low- and middle-income country immunization programs about the feasibility of M...

PATH has been collaborating with Vietnam National EPI to pilot the Digital Immunization Registry in one district in a Southern province under Optimize Project since 2012. In 2014, this system was expanded in all 164 Commune Health Centers in that province. It can help to reduce workload burden, incr...

Dose per Container Partnership (DPCP) The issue: Multi-dose containers are used to offer lower prices, higher supply volumes, and minimize cold chain storage and distribution requirements. As new, more expensive, vaccines are introduced in multi-dose presentations, maximizing the use of every dose ...

Dear TechNet Colleagues,   I would like to share with you a report on our latest cold chain maintenance investigation in Mozambique: "Why Fridges Fail Part 2: RTM Data for Maintenance". We are beginning to document how remote temperature monitoring data and dashboards can be used by maintenance t...

In cooperation with the Uganda Ministry of Health, PATH recently conducted a pilot study to document equipment failures in the Uganda National Expanded Programme on Immunization cold chain. Due to our use of purposeful sampling to locate a subset of failed cold chain equipment in Uganda, conclusion...

Hi all, I just wrote a blog on PATH's DefeatDD.org called "Getting to 'Mars' with immunization delivery," which I thought might be of interest! I really enjoyed the recent blockbuster movie,The Martian. Andas a vaccine advocate supporting PATH's advocacy for stronger immunization supply chains pro...

On day 4 of the TechNet Conference, I facilitated a roundtable discussion on what it takes to generate political will for supply chain improvements. At each table, participants shared their experiences generating political will and discussed in detail what it took to achieve meaningful change. Be...

VaxTrak in Vietnam VaxTrak helps health workers keep track of vaccine stock. In 2011, the Vietnamese National Expanded Programme on Immunization introduced VaxTrak in the provinces of Phu Tho, Quang Tri, and Ben Tre. This short video shows how VaxTrak works and examines the impact it has had. [you...

Dear Sir,Based on the PATH report, we must immediately demand from DCGI office or GOI for use of IPV through Intradermal Route as well, otherwise people would be cheated as they have been with Rabies vaccine. Though I disagree with the report on one point that is a device is required for effective d...

Thanks Julian. It really helped. I stress so much on anti freezing the H1N1 vaccine during my country wide lectures that I needed to be sure of my claims. Frankly it would have been better for a H1N1 vccine without VVM to be freeze resistant, as opertaionally it is much easier for vaccinators in ...

by Joanie Robertson, Technical Officer, PATH In March 2009, six companies submitted designs to PATH in response to its Battery-Free Solar Refrigerator Challenge. Product designs that meet desired specifications will receive financial assistance to cover the cost of third-party testing required for...

The Advanced Immunization Management (AIM) e-Learning website recently launched a new module to help decision-making on rotavirus vaccine introduction. The module provides comprehensive information from basic disease characteristics through immunization session planning; this interactive online to...
