Conventionally, stabilization of prophylactic vaccines have been a main attraction for the scientific and research communities. International health care organizations have provided funds for this effort for more than forty years. Moreover, stability has been linked with the temperature surrounding the vaccine vial, with not much attention being paid towards coinciding environmental parameters.
Recently, the advantages of the electronic time-temperature indicator [eTTI] have been well described. In all probability eTTI would not be proficient enough at monitoring the evaporative and radiative transfer of heat from the atmosphere. Monitoring temperature without a simultaneous estimate of humidity is often very erratic.
