4、mperature control is crucial,as most vaccines contain toxoid-based protein antigens that require precise structural integrity to elicit an effective immune response.Exposure to elevated temperatures can cause these proteins to unfold,aggregate,and degrade4,whereas freezing temperatures can result in
5、 the formation of ice crystals5,disrupting the protein structure and leading to irreversible denaturation.Beyond antigen stability,adjuvants such as aluminium salts play a key role in enhancing immune responses by promoting antigen-presenting cells activation and proliferation.Storage outside the sp
6、ecific temperature recommendations(typically 2-8C)can drastically alter the physicochemical properties of an adjuvant,resulting in a loss of immunogenicity and rendering vaccines sub-potent.Vaccines constitute a substantial portion of the global cold chain volume,with approximately five billion dose
