Mechanism of action

Aluminum hydroxide is a widely used vaccine adjuvant that works by creating a depot effect at the injection site, slowing antigen release and enhancing uptake by antigen-presenting cells. It activates the NLRP3 inflammasome and promotes a Th2-biased immune response, increasing antibody production and cellular immunity against the vaccine antigen. This mechanism makes it particularly effective in enhancing humoral immune responses in vaccine formulations.
