Table I.

Relative Serotype‐Specific Model Inputs for Transmissibility (R 0) and Paralysis‐to‐Infection Ratios (PIRs) by Serotype (Duintjer Tebbens et al., 2013)

Model Input Serotype 1 Serotype 2 Serotype 3
Relative basic reproduction number (R 0) for WPV or fully reverted VDPV (relative to serotype 1)a 1 (reference) 0.9 0.75
Relative R 0 of OPV parent strain to WPV or VDPV (relative to row above for same serotype)a 0.37 0.55 0.25
Average paralysis‐to‐infection ratio for fully susceptible individuals
  • WPV
  • OPV

1/2000.26 × 10−6

1/2,0001.2 × 10−6

1/1,0001.2 × 10−8

OPV = oral poliovirus vaccine; VDPV = vaccine‐derived poliovirus; WPV = wild poliovirus.

Thus, for a country with an assumed average R 0 = 10 for WPV1, this implies R 0 = 9 for WPV2, R 0 = 7.5 for WPV3, R 0 = 3.7 for OPV1, R 0 = 4.95 for OPV2, and R 0 = 1.875 for OPV3.
