Figure 2. Serum positivity rate (SPR), and geometric mean titer (GMT) in relation to vaccination status.

Figure 2

SPR and GMT in relation to number of vaccine doses (0–5), or previous TBE disease. The “0(ab)” group is individuals who decided not to get vaccinated because they knew they were antibody positive. (A) SPR for Enzygnost, Immunozym and RFFIT, (B) GMT with 95% CI measured using Enzygnost, (C) GMT with 95% CI measured using Immunozym. Both SPR (p<0.001, Fisher’s) and GMT (p<0.001, Dunn’s) was significantly higher after 4 and 5 doses compared to 3 doses, for all three assays.
