Abstract

The authors of the published article 'Correlation between Non-Polio Acute Flaccid Paralysis Rates with Pulse Polio Frequency in India' [...].

Highlights

Even the southern and northern parts of states such as Karnataka, with the same frequency of pulse polio campaigns, have widely variable non-polio Acute Flaccid Paralysis (AFP) rates
The frequency of administration of Oral Polio Vaccine (OPV) has increased due to routine immunization strengthening efforts, especially in northern states such as Uttar Pradesh and Bihar, stemming from campaigns such as special immunization weeks, Mission Indradhanush, and Gram Swaraj Abhiyan, which have been active from 2013/2014 onwards
The routine immunization OPV doses (5) are reaching a greater percentage of each birth cohort, which is not accounted for by the authors

Summary

Introduction

Even the southern and northern parts of states such as Karnataka, with the same frequency of pulse polio campaigns, have widely variable non-polio AFP rates. 4. The frequency of administration of OPV has increased due to routine immunization strengthening efforts, especially in northern states such as Uttar Pradesh and Bihar, stemming from campaigns such as special immunization weeks, Mission Indradhanush, and Gram Swaraj Abhiyan, which have been active from 2013/2014 onwards. The routine immunization OPV doses (5) are reaching a greater percentage of each birth cohort (about 30-40% more in northern states since 2013/2014), which is not accounted for by the authors.
