Consultant – IA2030 vaccine impact estimates project
( 2209344 )
Contractual Arrangement : External consultant
Contract Duration (Years, Months, Days) : 11 months
Job Posting: Oct 24, 2022, 3:18:39 PM
Purpose of consultancy
To provide technical and analytical input to the IA2030 vaccine impact estimates project team to incorporate additional features into the models.
The overarching goal of the Immunization Agenda 2030 (IA2030) vaccine impact estimates project is to update the modelled estimates of vaccine impact for the coming decade and document the methodology in a transparent manner. The output of this project aims to inform strategic priorities for the IA2030 and the 13th General Programme of Work (GPW13).
In April 2021, the IA2030 Vaccine Impact Estimates Team delivered the first iteration of vaccine impact estimates (Impact Goal indicator 1.1 “number of future deaths averted through immunization”) as part of the IA2030 Monitoring & Evaluation Framework for the 74th World Health Assembly. The estimates were used for advocacy during World Immunization Week 2021, the African Vaccination Week 2022 and WHO’s second investment case for 2022-2031.
For the subsequent phase of the project, the Team continues to improve the models and methods to improve upon the first iteration of estimates.
1) Generate modelled estimates of future deaths averted through immunization using Supplementary Immunization Activities (SIA) data:
- Develop criteria for defining and estimating appropriate population denominators;
- Develop approaches to handling SIA coverage rates;
- Prepare SIA coverage scenarios and datasets in collaboration with partners;
- Develop results, tables and figures for future deaths averted estimates for select pathogens using SIA data.
2) Develop morbidity measures to be incorporated into the first iteration of estimates based on 14 pathogens:
- Develop a modelling framework extended for Disability-Adjusted Life Year (DALYs).
3) Develop results, tables and figures for DALYs in line with deaths averted.
Develop model validation framework to refine the existing models as follows:
- Identify the weakness of the current modelling approaches by applying standard methods for model validation;
- Develop and implement novel approaches to model validation;
- Implement optimal approaches to utilizing the literature search on impact estimates from high-income countries; produce validation exercise results.
4) Develop and implement strategies to improve documentation and increase reproducibility within the current modelling framework in collaboration with the analytics team.
Qualifications, experience, skills and languages
- A first university degree in epidemiology, biostatistics, public health or other relevant disciplines.
- At least five (5) years of relevant experience in quantitative data analysis, including experience working with mathematical and/or statistical models in the field of immunization and vaccine-preventable diseases or other relevant areas.
- Experience preparing technical reports and manuscripts for peer-reviewed journals.
- Sound knowledge of mathematical and/or statistical models for estimating vaccine impact.
- Excellent data programming (preferably R programming language)
