Vaccination results in stronger HPV16-specific immune responses. The strength (median + interquartile range) of the indicated immune response to all 6 pools of HPV16 E6 and E7 peptides for the whole group measured before vaccination (pre-vac), after 2 vaccinations (2-vac) and after the 3^rd or 4^th vaccination (3/4-vac) is given. Only when the strength of the immune response was significantly different, this is indicated by the p-value. Measured was the vaccine-induced proliferation as indicated by the stimulation index using the lymphocyte stimulation test, the antigen-specific increase in the numbers of IFNγ-producing T cells by ELISPOT, and the antigen-specific production of cytokines (IFNγ, IL-5, TNFα and IL-10) in the supernatant of the lymphocyte stimulation test detected by cytokine bead array.
