​​​​This seminar will look at Vaccination Coverage Quality Indicators (VCQI) as a flexible resource for standardised coverage survey analyses, and discuss a case study providing insights on missed opportunities for simultaneous vaccination. ​
Household surveys are a vital source of data on childhood vaccination in low- and middle-income countries. To evaluate the effectiveness of government vaccination programs, the World Health Organization (WHO) has developed a set of outcome indicators that may be calculated from survey data.
​This talk describes a collection of Stata programs – called Vaccination Coverage Quality Indicators (VCQI) – developed at Biostat Global Consulting. These are made freely available by the WHO allowing survey analysts to calculate those indicators in a consistent and transparent manner from surveys that can vary in many specific details.
​As a specific case study, the speaker will describe recent insights from VCQI concerning a pattern of missed opportunities to administer inactive polio vaccine (IPV). The seminar will cover questions including:
- ​How was the pattern detected?
- ​Is it a local aberration or a widespread issue?
- ​What is the prevalence of missed doses?
- ​When the doses are indeed missed, how many are only short-term delays and how many of those children do not come back to the clinic and therefore do not receive the dose later? ​
