Cold Chain Storage of Vaccines: A Brief Introduction to Thermometry

Author(s)
Abstract
To maintain the efficacy of vaccines requires maintaining the storage temperature within well-defined limits; vaccine failure due to improper storage results in large direct and indirect public health costs. In this presentation, I give a brief introduction to thermometry and related techniques in measurement science. Topics covered include: a description of the measurement problem; an overview of sensor types; a description of what it means to have traceability to NIST; methods for measurement assurance; measurement uncertainty and error allowances; the difference between certification and calibration; and the proper use of thermometers. At the end of the talk, I give answers to a number of common questions regarding temperature measurements and traceability within the vaccine cold chain.Citation
