title: [Application of immunization products database in calculation of cold chain capacity needs].
abstract: OBJECTIVE
  To explore the method of calculating cold chain capacity needs by using Immunization Products Database (IPD).
  
  
  METHODS
  Calculating cold chain capacity needs by multiply vaccinated doses and dose volume from IPD, considering the influence factors of stock setting and space usage.
  
  
  RESULTS
  Calculated based on the cold chain capacity needs equation, the annual chain capacity needs for a county Center for Disease Control and Prevention of Shanghai are 23.6M3, which is sufficient to the cold storage house capacity.
  
  
  CONCLUSIONS
  Cold chain capacity needs for immunization program can be precisely measured with dose volume from IPD and vaccinated doses based on IPD products code, which will provide scientific evidence for cold chain equipment.
