This study aimed to investigate whether a combination of monophosphoryl lipid A (MPL, a TLR4 agonist) and polyriboinosinic polyribocytidylic acid (poly I:C, a TLR3 agonist) can enhance the protective efficacy of an inactivated A/Puerto Rico/8/1934 (A/PR8) H1N1 influenza vaccine against homologous influenza infection and minimize illness outcomes. Results showed that combination MPL and poly I:C adjuvanted influenza vaccination increased the production of antigen-specific antibodies, decreased the levels of cytokines and cellular infiltrates at the infection sites, and induced significant memory T and B cell responses in mice. The results of this study suggest that the combination of MPL and poly I:C can be developed into a possible adjuvant for enhancing the efficacy of influenza vaccines.","Author":"Chau Thuy Tien Le, So Yeon Ahn, Thi Len Ho, Jueun Lee, Dong-Ha Lee, Hye Suk Hwang, Sang-Moo Kang & Eun-Ju Ko ","PublicationDate":"2023.07.28","DOI":["https://doi.org/10.1038/s41598-023-39210-6"]}
