在测试集中，正常细胞的识别率为96%，LSIL细胞识别率为94%，HSIL细胞识别率为100%，癌细胞识别率为88%。

In testing set, the recognition rate was 96% in normal cells, 94% in LSIL cells, 100% in HSIL cells, and 88% in cervical cancer cells.

他们将研究目标确定为训练免疫系统识别和攻击携带这些肽链的癌细胞。另外，该疫苗也将含有提高免疫反应的物质。

The goal is to train the immune system to recognize and attack cancer cells bearing these peptides; the vaccine would also contain substances designed to boost immune response.
