We hypothesized that enhanced delivery of peptide antigens to, and uptake in, secondary lymphoid tissues should elicit more robust CD8+ and CD4+ T cell responses and improved anti-tumor responses. Here, we have designed SLP-containing cationic lipoplexes (SLP-Lpx) that improve delivery of peptides to myeloid cells in the spleen and lymphatics. Using the G12D KRAS mutations as neoantigens, we found that vaccination of mice with naked synthetic peptides harboring the G12D mutation with CpG adjuvant stimulated mainly CD4+ T cell responses with limited tumor growth inhibition. On the other hand, immunization with SLP-Lpx stimulated both CD4+ and CD8+ T cells and suppressed tumor growth in a CD8+ T cell-dependent manner. Combination of the SLP-Lpx vaccines with a checkpoint inhibitor led to profound growth suppression of established tumors. These studies suggest that preferential targeting of peptides derived from neoantigens to the spleen via lipoplexes elicits potent CD4+ and CD8+ T cell responses that inhibit tumor growth.Anecdotal evidence suggests that Coronavirus disease 2019 (COVID-19), caused by the coronavirus SARS-CoV-2, exhibits differences in morbidity and mortality between sexes. Here, we present a meta-analysis of 3,111,714 reported global cases to demonstrate that, whilst there is no difference in the proportion of males and females with confirmed COVID-19, male patients have almost three times the odds of requiring intensive treatment unit (ITU) admission (OR = 2.84; 95% CI = 2.06, 3.92) and higher odds of death (OR = 1.39; 95% CI = 1.31, 1.47) c
