Monitoring of vaccine storage in Vietnam

About our client

Temperature monitoring in Vietnamese hospitals is critical for maintaining the safety and effectiveness of medical supplies and ensuring patient comfort. In Vietnam, as in many countries, specific requirements and best practices must be followed to meet international healthcare standards.
The World Health Organization (WHO) and the International Society for Pharmaceutical Engineering (ISPE) have introduced guidelines for maintaining proper temperature control.

The Vaccination Department of Dong Nai General Hospital was established to meet the needs of protection; health care of people. Help patients conveniently go to the hospital for examination; treatment and vaccination to prevent diseases.

The Dong Nai Disease Control Center is directly under the Department of Health, composed of: the Reproductive Healthcare Center, the Maxillofacial Center, the Preventive Medicine Center, the International Health Center Quarantine Center, the HIV/AIDS Prevention Center, the Health Education and Communication Center, and the Occupational Health and Environmental Protection Center.

PROBLEM TO SOLVE / TASK

Most healthcare facilities, including those in Vietnam, are required to follow global standards for temperature control, such as those from the World Health Organization (WHO) and the International Society for Pharmaceutical Engineering (ISPE). Sensitive items like vaccines and medications require precise temperature ranges. For instance, vaccines often need to be stored between +2°C and +8°C.
Continuous Monitoring: WHO recommends 24/7 monitoring using electronic temperature monitoring devices, especially for cold storage facilities.
Alarm Systems: Facilities should implement alarms to alert staff to any temperature excursions.
Detailed logging of temperature data is critical for compliance, ensuring that any deviations are immediately addressed and documented.
WHO requires that all storage and monitoring equipment undergo calibration and regular maintenance to guarantee accuracy.

SOLUTION

The equipment was supplied and installed by TIN VIET ENGINEERING TECHNOLOGY COMPANY LIMITED
The Efento system meets all legal requirements, wireless sensors measure temperature, and send the data to a gateway which transmits it to the Efento Cloud platform. Efento Cloud collects the sensor data and allows users to visualize it, automatically generate reports and notify the hospitals’ personnel, if the temperature is out of the safe range.

Efento Cloud is a cloud based platform, what provides quick scalability, security and safety of the data.  The platform is updated and monitored by Efento team, what gives the customers and users peace of mind. The data is constantly backed up in a data centre in a different geographical location than the main servers, to ensure that it will always be available for the customers.

 Moreover, the personnel has direct access to the measurements using a free Efento mobile application.

Results

Hospitals has solved the problem of temperature monitoring, obtaining operational reliability and data security.

Authorized people have access to current measurements from anywhere.

The customer does not bear any additional subscription or maintanence costs.

To expand the system, only the purchase of sensors is required, because one gateway can work with over 120 sensors.

The existing structure also allows for connection of temperature sensors in liquid nitrogen tanks, differential pressure sensors for monitoring clean rooms (operating rooms, rooms for storing transplantological preparations).

Many Vietnamese hospitals have used this solution and are very satisfied with its functionality. Some typical clients are: Duc Khang Hospital. 175th Military Medical Hospital. Vimedimex. Dong Nai Hospital. CDC Dong Nai. Gene Solutions…

New gateway BLE/LTE for transport
The device features an IP67 enclosure and transmits data from compatible BLE loggers directly to the cloud.
Power supply: 5V DC / 1A, USB-C, backup battery: LI-Po, 3200 mAh (up to 12 hours backup power).

Efento Cloud for hospitals – safety, savings and full control
A hospital consists of thousands of processes, devices, and rooms whose proper functioning is essential for patient safety. One of these is ensuring proper storage conditions for medicines, vaccines, medical supplies, and laboratory samples.
Efento devices can also monitor gas and liquid pressure, water leaks, and visitor footfall.
Efento Cloud enables automated monitoring and control.
Automated pressure warning systems
Pressure sensors are installed in water, oil, chemical, or compressed air pipelines for continuous pressure monitoring. In the event of a pressure issue, a PLC controller operates a pump or valve to immediately increase or decrease the pressure. However, most pressure sensors only provide control signals and lack alerting capabilities.
Differential Pressure Monitoring in Vietnam
The facility was originally equipped with analog differential pressure gauges, which did not allow for remote monitoring or automated record-keeping to document production conditions.
Is it necessary to archive reports from the Efento system?
Data from temperature loggers used in the storage and transport of vaccines must be kept for at least 5 years. In the case of the Efento system, measurement data from the loggers is stored for 6 years. To ensure that nothing is lost (e.g., due to a failure), it is simultaneously saved in two independent data centers (AWS servers).
We were busy deploying 150,000 NB-IoT sensors – The Things Conference
The 9th edition of The Things Conference—the premier global IoT event held on September 22–23, 2026, in Amsterdam—brought together over 2,500 experts from around the world.
We are proud to have been a Bronze Partner of this conference.
