Low-cost freeze-protected carrier

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 incorporated water as a phase change barrier between the stored vaccines and the ice packs. This appears to be the same freeze protection mechanism incorporated in the PQS approved carrier. T...

BID Initiative's total cost of ownership study: The importance of costing data for building sustainable electronic immunization systems

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 EIRs in Tanzania and Zambia. This sort of costing information helps countries budget for and plan for expansion.

New reports on harvesting unused energy from SDD installations

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 primary SDD appliance load must be prioritized above any other load. WHO and other organizations have been working to define how this can be done safely and reliably. In support of WHO/PQS, P...

Continuing the Conversation: Improving Immunization Supply Chains to Close the Immunization Gap

A well-functioning supply chain often goes unnoticed. People rarely talk about fully stocked shelves at the store or on-time delivery of a package. It’s the interruptions to the supply chain that get noticed. As they say, “the squeaky wheel gets the grease”. These days, immunization supply chains (iSC)—the network of staff, equipment, vehicles, and data needed to get vacc...

Microarray patches for dermal delivery of vaccines

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 MAPs to facilitate immunization, especially for novel delivery scenarios like self-administration of vaccine at home, as well as more traditional immunization settings in LMICs. We hav...

Expanding Digital Immunization Registry in Vietnam

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, increase data accuracy and more importantly increase on-time vaccination rates. This intervention has been awarded the Health Innovation Award, a partnership between GSK and Save the Children in 2015. ...

Dose per Container Partnership (DPCP) an update

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 in a container increases in importance. HCWs need to be more strategic about when to open a container; diligent about how they care for open containers, and potentia...

Uganda Equipment Failure Investigation Report

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, conclusions about predicted failures cannot be drawn from our study report. However, after learning of the failures, one manufacturer (B. Medical) has agreed to replace the equipment assessed.

Dose per container partnership (DPCP) launched

Earlier this month, the Dose Per Container Partnership (DPCP) project was launched. This Bill and Melinda Gates Foundation project is implemented by JSI and partners (PATH, Agence de Médecine Préventive (AMP), Clinton Health Access Initiative (CHAI), HERMES modelling team and the International Vaccine Access Center (IVAC) / Johns Hopkins University).

The project will help identify evidence needed to support better-informed decision making related to the trade-offs between cost and hea...

PATH Study on Intradermal IPV- needs implementation

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 delivery of vaccine as this can be done with needle and syringe as well in India as we are doing with BCG/ ARV. also I disagree with the report that the needle syringe method would cost more, especiall...

Technical and commercial feasibility of stabilizing vaccines: PATH study

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 countries like ours to keep a vaccine close to ice and hence close to 0 or below than to keep it close to +2-+8C. Thanks again Best regards...

New online tool for rotavirus vaccine decision-making

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 tool is primarily aimed at immunization program managers but will also be useful for country program officers, medical providers, public health educators, and public health managers. Developed by PATH...
