To compare the difference of immune response induced by egg-based and cell-based H1N1 influenza vaccines.
C57BL/6 mice were injected subcutaneously with H1N1 influenza vaccines produced from eggs or MDCK cells, respectively. The cellular and humoral immune responses induced by two type of vaccines were detected by using methods such as serological test, intracellular cytokine staining and multiplex cytokine detection assay.
In terms of humoral immunity, the serum titer of the cellular vaccine group was basically the same as that of the chicken embryo vaccine group. As to cellular immunity, the secretion level of immune-related cytokines in the cellular vaccine group was more significant.
Due to the different culture media, the two monovalent influenza vaccines have certain differences in the induction of immune response. Cellular vaccine has the advantage of inducing multiple immune responses, and the combination of other advantages of cellular technology indicates that the use of cellular technology will become a trend to produce influenza vaccine. This study is helpful to evaluate the immune level in mice induced by monovalent influenza vaccines prepared with different substrates.
