We developed a simple method of freeze prevention. The method involves the placing of wet towels between the vaccines and the ice packs. The phase change "coolth" absorbing properties of the wet towel keep the ice packs from freezing the vaccines.  Freezing can also be prevented by placing insulation between the ice packs and the vaccines. However, with this method there is poor thermal coupling between the ice packs and the stored vaccines, which results in the vaccines warming up more rapidly when the ice packs are partially melted. The wet towel method will keep the vaccines colder longer.  We carried out some tests to measure the effectiveness of the wet towel method and found it quite effective. The tests consisted of placing -15C ice packs in an insulated envelope. The ice pack was separated from a temperature probe by a wet towel and the temperature of the probe was monitored. The probe stayed above freezing.  Feel free to contact us if you need additional information.  Larry Schlussler, PhD  Sun Frost
