Remote Temperature Monitoring of Tanzania's Vaccine Cold Chain Improves Visibility into Equipment Performance

Remote temperature monitoring (RTM) is an important part of the cold chain system for vaccines to ensure their potency. In Tanzania, the Ministry of Health (MOH) made a significant investment in cold chain equipment (CCE) for the vaccine supply chain and rapidly expanded vaccine availability, creating an opportunity to also invest in more proactive monitoring of CCE performance. The country’s experience so far with RTM demonstrates the promises and challenges of this technology, as well as highlights what factors should be considered when implementing or scaling up this monitoring approach to improve performance and manage risks.
