Table 3 PV seroprevalence of IPV-immunized children compared to OPV-immunized children in a previous study [10]

From: A national cross-sectional study for poliovirus seroprevalence in the Republic of Korea in 2012: implication for deficiency in immunity to polio among middle-aged people

  No. of samples (%)
All positive PV1-negative PV2-negative PV3-negative All negative
IPV-immunized children (6–10 years, n = 236) 195 (82.6%) 16 (2.6%) 8 (1.0%) 29 (7.5%) 3 (1.3%)
OPV-immunized children [10] (6–11 years, n = 500) 411 (82.2%) 13 (6.8%) 5 (3.4%) 38 (12.3%) 0 (0%)
P value* >0.05 <0.01 <0.05 <0.05 <0.05
  1. *P < 0.05 indicates significant differences of seroprevalence among the compared groups.
  2. IPV, inactivated polio vaccine; OPV, oral poliovirus vaccine; PV, poliovirus.
