a The GO analysis on DEGs induced by the third dose of BBIBP-CorV in elderly groups and the top 20 enriched terms in the biological process were shown. b The GO analysis on DEGs induced by the third dose of ZF2001 in elderly groups and the top 20 enriched terms in the biological process were shown. c The GO chordal diagram showed the degree of differential expression changes of genes involved in each functional project. Criteria: p-value < 0.05. d The GO chordal diagram showed the degree of differential expression changes of genes involved in each functional project. Criteria: p-value < 0.05
