While the elicited tier 2 neutralizing antibodies (nAbs) showed variability in durability, especially at lower doses, the findings emphasize the importance of dose-dependent adjuvant strategies in achieving effective immune memory. Dose-dependent effect of SMNP adjuvant: Varying doses of QS-21\u2013containing SMNP (25, 50, 200, or 400 \u03bcg) influence T FH -driven B cell responses to a stabilized envelope (Env) trimer, BG505 MD39. Higher SMNP doses enhanced Env-specific CD4+ T cell responses, with the 400 \u03bcg dose driving the strongest Th1 and T FH differentiation. Bone marrow plasma cells (BMPCs) were assessed 13 weeks after the final boost, the 200 \u03bcg and 400 \u03bcg groups achieved 100% BMPC responses.<\/span><span data-ccp-props=\"{&quot;134233279&quot;:false,&quot;201341983&quot;:0,&quot;335551550&quot;:6,&quot;335551620&quot;:6,&quot;335559685&quot;:720,&quot;335559739&quot;:120,&quot;335559740&quot;:240}\">\u00a0<\/span><\/li>\n<\/ul>\n<ul>\n<li data-leveltext=\"\uf0b7\" data-font=\"Symbol\" data-listid=\"5\" data-list-defn-props=\"{&quot;335552541&quot;:1,&quot;335559685&quot;:1080,&quot;335559991&quot;:360,&quot;469769226&quot;:&quot;Symbol&quot;,&quot;469769242&quot;:[8226],&quot;469777803&quot;:&quot;left&quot;,&quot;469777804&quot;:&quot;\uf0b7&quot;,&quot;469777815&quot;:&quot;hybridMultilevel&quot;}\" aria-setsize=\"-1\" data-aria-posinset=\"3\" data-aria-level=\"1\"><span data-contrast=\"none\">Clinical implications: This macaque study offers important insights into the impact of adjuvant dosing on immune responses and is expected to inform future vaccine platform design.
