Finding the Perfect Temperature for Vaccines

Finding the Perfect Temperature: Protecting Lifesaving Vaccines in Remote Areas


Immunization is one of the most successful and cost-effective public health interventions in history, saving 2-3 million lives every year. In Tanzania, JSI is installing remote temperature monitoring devices to strengthen the immunization cold chain and ensure that vaccines make it to the last mile. 

DIGITALLY MIMICKING THE ANALOGUE FUNCTION OF A VVM

Imagine that VVM’s do not exist. As an alternative a tiny electronic device could be developed which would record the temperature history of the vaccine vial. The device would be attached to the vial and graphically display the temperature history of the vaccine. If a health worker wanted to know how the temperature history of the vaccine would affect its life, how would they do it? This is essentially the same problem faced when trying to interpret the data obtained from a refrigerator or va...

Realtime Cooler Temperature & Location Monitoring in the Field

All,

I am trying to solve the following problem...

We have small medical teams that travel to remote locations, to deliver vaccines to patients.

Many of the routes are through jungle, mountains, dessert, etc and take several hours or longer to reach to destination.

The teams use motorbikes, and walking through rough terrain to get to the destination.

During the traveling, there is no way to tell what's going on in the cooler until the team reaches the d...

Temperature monitoring devices and Thermostat for vaccine refrigeration system

Dear Technet members,

I would like to share my thoughts on the temperature monitoring devices and thermostal for vaccine refrigeration system.

In the early days of EPI, temperature of the refrigerator was measured and displayed by a simple analogue thermometer which was either a bi-metal or stem type alcohol thermometer.  Twice daily the health worker records these temperature on the temperature monitoring sheet and posted on the door of the fridge.  Filled temperature records...

Cartographie de la température de Chambres froides au Niger

Bonjour

Le Niger a entrepris en 2016 avec l'aide de ses partenaires la cartographie de la température dans ses Chambres froides. Nous avons beaucoup appris de cette expérience notamment sur :

- La cartographie de toutes les chambres froides qu'elles soient anciennes ou nouvelles

- Le réglage de la consigne d'arrêt des unités de réfrigeration

- La fiabilité du Kit Berlinger (SmartView)

Nous proposons les recommandations suivantes à d'autres pays intéress...

“CROWD TESTING” An Easily Implemented Method of Ice Pack Conditioning

Vaccines can tolerate temperatures above 8 deg C however temperatures below 0 deg C will freeze a vaccine and it will lose it’s efficacy. At temperatures above 8 deg C the life of a vaccine will be lowered but the exposure will not be catastrophic. For the most sensitive vaccine, VVM II, the life of the vaccine will decrease from 104 days to 99 days when exposed to 20 deg C conditions for one day. For a VVM7 vaccine exposed to the same one day temperature excursion the life of the vaccine wil...

Passive storage devices--new technology requires new SOPs

Does anyone have experience with vaccine passive storage devices in the field? We are piloting the PQS pre-qualified Arktek device in three rural health centers. By design, the device maintains a temperature range between 0°C and 10°C which will not freeze the vaccines so should not pose any risk to the potency of the vaccines. We are seeing some unease from health workers and EPI managers, though, who are concerned that vaccines would be out of the 2°C – 8°C range and at risk of freezing, ev...

Remote temperature monitoring (RTM); Accelerate scale-up !

It's a mystery to me, considering that manual temperature monitoring of vaccine stores using monthly charts and glass thermometers was the first MIS achievement of the EPI in the last 4 years of the 1970s - yet the first Remote Temperature Monitoring (RTM) studies were 10 years ago and only a handful of countries have implemented RTM today. The benefits of the manual monitoring in 1976 were simple, clear and motivating. Those of the RTM should be even more enticing. Temperature recording is a...

VVM colour change as a continuous progression

WHO has just released a new infographic that summarises how health workers can use vaccine vial monitors (VVMs) to decide whether or not to use a vaccine vial. Most notably, it presents VVM colour change as a continuous progression, rather than as four distinct stages.



A VVM is a chemical indicator label attached to the vaccine container (vial, ampoule or dropper) by the vaccine manufacturer. As the container moves through the supply chain, the VVM records its cumulat...

VVM’s and MKT Thermometers

Below are some examples of how an MKT thermometer could be used to to simpllfy temperature data analysis for the cold chain.

If the temperature in a refrigerator is 4 deg C for 20 hours then increases to 15 deg C for 4 hours, how will the vaccine life be affected?

- If this is a one day occurrence – should an alarm be set off to notify a repair person?

- If this temperature variation occurs everyday for a month – will it be problematic?

- If on a 24 day excursi...

Your phone rings; it’s the freezer calling

by Olivier Ronveaux, WHO, and Mojtaba Haghgou, Vaccine Management Consultant Maintaining required temperatures in vaccine refrigerators and freezers is one of the more thankless tasks of a cold chain manager as it requires painstaking manual recording of the temperature of each piece of equipment twice daily. Despite the monotony, temperature monitoring is a crucial task, especially in central stores at the national level where millions of doses of costly vaccines are at stake. A
