WHO supported networks measuring COVID-19 vaccine effectiveness

Project description

Epiconcept provides technical support on implementation of a COVID-19 and influenza vaccine effectiveness (VE) networks for the WHO European Region, WHO Regional Office for Africa, and WHO Regional Office for the Eastern Mediterranean Region including collection, collation and analysis of country level health care worker (HCW) VE and Severe Acute Respiratory Infection (SARI) VE studies; and support to WHO Europe in the meta-analysis and pooling of SARI and HCW VE studies for the WHO Region

Context situation

Following the rollout of COVID-19 vaccines, it was key to monitor their effectiveness in different settings, including low and middle income countries. Vaccine effectiveness results are essential to guide vaccination policies.

Project activities

Development of generic vaccine protocols effectiveness.

Epiconcept developed two generic protocols to measure the effectiveness of vaccines 1/ at preventing SARS-CoV-2-associated hospitalization (test-negative design) 2/ SARS-CoV-2 symptomatic infections among health care workers (cohort study)

Technical support to countries conducting vaccine effectiveness studies

Technical support to collect, collate and analysis of country level health care worker (HCW) vaccine effectiveness studies and Severe Acute Respiratory Infection (SARI) vaccine effectiveness studies

Pooling and aggregation of data at regional level

Support the three WHO Regional Offices in the meta-analysis and pooling of SARI and HCW VE studies

Capacity building for vaccine effectiveness studies

Organizes technical workshops, trainings, develop scripts for data management, data checking and data analysis for countries conducting vaccine effectiveness studies
