Abstract: We conducted the first US study using graphic-output temperature data loggers in quantifying cold chain failure. Fifty-four vaccine refrigerators of a county outpatient health system were studied. Fortyeight percent maintained temperatures of 2°C to 8° C and 24% had protracted periods of temperatures less than 0°C. The correlation between the percentage of refrigerators with freezing temperatures and the pertussis rate for each health region was r=0.76. The findings suggest that improper vaccine storage may have contributed to recent increases in pertussis rates.
