protein antigens in solution; the resulting precipitate improves vaccine immunogenicity
by facilitating the slow release of antigen from the vaccine depot formed at the site
of inoculation.;
Alternative definition : NCI-GLOSS: A chemical substance that contains aluminum sulfate and a second chemical,
usually potassium sulfate. It is used to shrink tissues, to stop bleeding, and to
boost the immune response to a vaccine.;
