Monitoring the Canine Vaccine Cold Chain in the Field

Monitoring the Canine Vaccine Cold Chain in the Field

Abstract: The World Health Organisation stresses the importance of maintaining the cold chain for temperature sensitive vaccines. Due to the recommendation for rabies vaccines to be stored between 2° and 8° Celsius and the nature of canine mass vaccination projects, cold chain maintenance remains one of the most significant logistical hurdles project managers have to overcome.

Mission Rabies field teams in Picture4Malawi evaluated the use of adhesive temperature monitors as an alternative to thermometers in both storage fridges and field cooler boxes during the duration of a 4 week mass vaccination drive in April/May 2016.

Two different Timestrip® temperature monitors were used to alert the teams to the critical temperature thresholds of 0°C and 30°C.  As freezing rapidly damages vaccines, each vaccine box containing 10 vials of 10ml vaccine was marked with a monitor that indicates the immediate crossing of the lower threshold through colour change. As damage from high temperatures is related to both the temperature achieved and the time of exposure, to test for the upper temperature limit each cooler box was equipped with a monitor that showed the crossing of the upper threshold over time.

Of a total of 22 vaccination teams participating in the study, 7 teams reported an exposure of the vaccines to temperatures above 30°C for more than 4 hours and on 9 occasions teams reported a temperature drop to 0°C or below.

These findings highlight the importance of monitoring the temperature during field campaigns, both due to proximity to ice packs and exposure to high outside temperatures. The use of Timestrip temperature indicators gives early visual clues and raises awareness among the team. However practicability of the temperature monitoring must be taken into consideration and adhesive monitors need to be improved with regards to their setup to make them a valuable tool in field projects.

This abstract was presented at the 28th Annual Rabies in The Americas Conference on 23 October 2017.

Using the App simply involves taking a photo of a Timestrip® label with a smartphone.

If the Timestrip® has a new style serial number, the App will recognise the serial number and allow you to register it on the system.

You can then take a follow on scan where you can enter its activation state (inert, activated or breached), storing this data with essential time and location information in the cloud.

If the Timestrip® has an old style serial number you can still use the app in the same way but you’ll need to manually enter the serial number. The App is free to download from the Google Play store with an iOS version to follow shortly.

High tech low cost

The App is the latest innovation from Timestrip, which revolutionised the field of cold chain management with its unique Irreversible Time and Temperature Indicator labels (TTIs).

Recognised by the World Health Organisation and the US FDA as an essential tool for the cold chain management of blood and food products, TTIs provide data as to whether a blood or food product is safe to use. Timestrip’s irreversible TTIs make this crucial safety information unambiguous and instantly visible.

Like having a hundred permanent digital data loggers

The main benefit of Timestrip’s irreversible TTI labels is that they give essential cold chain management information on individual units of processed products. This deals with the main shortcoming of digital data loggers, which are mostly used for containers of transported and stored products.

Thanks to the new Timestrip® App, extra key information around cold chain management is added with the safe storage of status, time, journey and location data, which can be accessed at any time via the app or via a website. A digital data logger can be lost or damaged and all its data can be wiped clean. The Timestrip® App however safely stores this data in the Cloud.

Data logger functionality at a fraction of the price

Timestrip UK CEO Reuben Isbitsky says: “I am very excited about our first App, which brings Timestrip TTI labels very close to data logger functionality, at a fraction of the price.  While a key benefit of Timestrip products is that they do not need external infrastructure to read and interpret, using the optional Timestrip Temperature App to scan them, adds enhanced functionality, easy audit trail and provides the customer with a permanent record of the history of the product’s journey.”

New vaccination reminder band made possible by Timestrip & Trust for Vaccines and Immunization (TVI)

tvi-logoTimestrip UK Ltd has announced it is working with Trust for Vaccines & Immunization (TVI), a not-for-profit organization, established to help ensure that every child, irrespective of his/her social class, colour or ethnic group is protected against Vaccine Preventable Diseases in Pakistan and around the world.

Bill & Melinda Gates FoundationTVI is the recipient of a Bill & Melinda Gates Foundation Grand Challenges Explorations Award to develop a Vaccine Indicator and Reminder (VIR) band and is working in collaboration with Timestrip to develop the innovative device, reminding parents for timely completion of their children’s vaccines.

Working in partnership with Timestrip® and design consultants Daylight, Dr. Noor Sabah Rakshani from TVI has created the Vaccine Indicator Reminder (VIR) band to provide a simple, low-cost method of showing when each of the three rounds of vaccines needed over the first 14 weeks of a child’s life are due, alerting the mother with a clear visual marker at 6, 10 and 14 week intervals.

VIR band being put on an infant

Whilst the World Health Organisation estimates that vaccinations help save over 2.5 million lives each year globally, figures indicate that up to 60% of children in Pakistan do not complete the immunization schedule.

Those with a vaccination reminder card achieve above 80% vaccination completion but if no card is available, or if the card is lost or damaged, the child may miss a lifesaving vaccination.

This new ‘wearable’ healthcare reminder solution is being heralded as a breakthrough solution, thanks to the revolutionary application of a Timestrip® indicator manufactured into the durable, soft plastic waterproof VIR band, which is attached to the baby’s ankle.

Each VIR band is marked with a unique number to match the child’s medical records at the point of issue.

The failsafe and irreversible nature of the Timestrip® technology (activated by simple finger pressure) shows each of the 6, 10 and 14 weeks vaccination milestones.

As the highly visible red indicator liquid (a food grade dye) sealed inside the Timestrip® migrates along the clear window, the three vaccination periods are graphically marked.

Timestrip’s patented ‘liquid’ technology ensures the accurate passage of elapsed time over the entire 18 week period.

Gates Foundation Vaccine Reminder BandThere are no moving parts or electronics, just good science helping mothers and carers follow their child’s vital vaccination program with nothing but a quick glance at their baby’s ankle.

Dr. Noor Sabah Rakshani is excited at the progress made since the first VIR Bands were shipped to Pakistan late last year.

“We started our community effectiveness trial on October 28, 2014 in four study sites in Karachi, Pakistan. As of February 2015 the team has enrolled 344 children in the intervention and control groups, with 200 wearing the VIR band and 144 children in the control group receiving only the routine immunization card.

We have started receiving input from the parents as they come back for their second and third doses of the vaccine at 6, 10 and 14 weeks time.

Aside from the vital funds and invaluable support this pilot study has received from the Gates Foundation, an application for a GAVI grant to introduce the VIR band through a community midwifery program is also in the works.

The idea is for every midwife to give an activated VIR band to every infant they attend to in the community, and the VIR band will indicate to the parents the ‘Number of Weeks Unprotected’ for their child.

We are taking small but very important steps in our quest to protect children from vaccine preventable illnesses across Pakistan and around the world. The environmental friendly low cost and widely used Timestrip® technology has made it possible for the VIR band to be tested in low income communities in Pakistan and and I am thrilled to be working with the team.”

Commenting on the VIR band project, Timestrip® Founder Reuben Isbitsky said:

“We have a long history of innovation in the medical and pharmaceutical sectors, including the development of temperature monitoring products for blood products and vaccines. This project has allowed us to support the creation of a simple but life-saving product that could help millions of children who suffer through incomplete vaccination regimes. We are absolutely delighted to be helping bring about change in this vital area of work.”
