Important new knowledge about the effect of aluminum adjuvants on the immune response in terms of their impact on cytokine profiles, uptake by antigen-presenting cells (APC), and surface marker expression has been published in recent years. However, although the knowledge about these adjuvants is thus more comprehensive now than ever before, the user is often still confined to a more empirical approach when confronted with practical issues when it comes to the handling and use of these adjuvants. In this chapter we have given focus to the user's perspective, discussing practicalities like dosage, temperature stability, relevant monographs, and preparation with antigen.

Antigens Involved in Adaptive Immunity

An antigen is any substance the immune system identifies as foreign and potentially harmful to the body, prompting an immune response. Antigens have two functional properties: immunogenicity and reactivity. Immunogenicity is the ability of an antigen to stimulate a specific immune response. At the same time, reactivity describes the antigen's ability to react with the cells and antibodies produced in response to it.

Vaccines

Vaccines are among the most effective tools in preventive medicine, designed to prepare the immune system to recognize and combat infectious agents. By introducing antigens—substances that the immune system identifies as foreign—vaccines stimulate an adaptive immune response that leads to immunological memory. This immunological memory enables the body to mount a faster and more effective response upon future exposures to the actual pathogen.Vaccines can be categorized based on the type of...
Vaccine Production01:23

Vaccine Production

Vaccine production involves a sequence of upstream and downstream processes to generate a safe and effective immunological product. It begins with cultivating microorganisms, such as viruses or bacteria, to obtain antigenic material. For viral vaccines, mammalian host cells are grown in bioreactors and subsequently infected with the target virus. The virus replicates within the host cells, which are lysed to release viral particles. This lysate is then clarified through filtration or...
