The cytotoxicity of MNCs from peritoneal tissue was significantly enhanced after repeated vaccinations.

Group	2 × 90d*	3 × 90d*	2 × 60d**	3 × 60d**	2 × 30d***	3 × 30d***

^a p-value: group compared to group vaccinated once 90, 60 or 30 days before tumor challenge

* vaccination started 90 days before the injection of viable tumor cells; the vaccine was applied once (1×), twice (2×) or three times (3×) in 15 days interval

** vaccination started 60 days before the injection of viable tumor cells; the vaccine was applied once (1×), twice (2×) or three times (3×) in 15 days interval

*** vaccination started 30 days before the injection of viable tumor cells; the vaccine was applied once (1×), twice (2×) or three times (3×) in 15 days interval, except for the last - third vaccination, which was performed 7 days after second vaccination
