Evaluating the effectiveness of COVID-19 vaccines during a period of Omicron variant predominance among Bangladeshi population: A test-negative design measurement.

The study was conducted to estimate the protective effectiveness (PE) of complete primary or booster dose regimens of COVID-19 vaccines deployed in Bangladesh. The study was conducted in four hospitals in Dhaka between December 30, 2021, and August 31, 2022 following a test-negative design. Patients aged ≥18 years attended with COVID-like symptoms were enrolled and tested for RT-PCR.

Evaluation of oral cholera vaccine (Euvichol-Plus) effectiveness against in Bangladesh: an interim analysis.

Introduction: Millions of Euvichol-Plus doses have been deployed from the global oral cholera vaccine stockpile in over 20 cholera-affected countries. However, information on Euvichol-Plus's effectiveness is limited. Using this vaccine in a cholera epidemic in Dhaka, Bangladesh, provided the opportunity to evaluate the vaccine effectiveness (VE) using a test-negative design.

Diarrhea Case Surveillance in the Enterics for Global Health Surveillance Study: Epidemiologic Methods.

Background: is a leading cause of acute watery diarrhea, dysentery, and diarrhea-attributed linear growth faltering, a precursor to stunting and lifelong morbidity. Several promising vaccines are in development and field efficacy trials will require a consortium of potential vaccine trial sites with up-to-date diarrhea incidence data.

Methods: The Enterics for Global Health (EFGH) surveillance study will employ facility-based enrollment of diarrhea cases aged 6-35 months with 3 months of follow-up to establish incidence rates and document clinical, anthropometric, and financial consequences of diarrhea at 7 country sites (Mali, Kenya, The Gambia, Malawi, Bangladesh, Pakistan, and Peru).

The Enterics for Global Health (EFGH) Surveillance Study in Bangladesh.

Background: is an important cause of diarrhea in Bangladeshi children <5 years of age, with an incidence rate of 4.6 per 100 person-years. However, the report was more than a decade old, and data on consequences are similarly outdated and heterogeneously collected.

Quantifying the Cost of Diarrhea in the Enterics for Global Health (EFGH) Surveillance Study.

Background: Comparative costs of public health interventions provide valuable data for decision making. However, the availability of comprehensive and context-specific costs is often limited. The Enterics for Global Health (EFGH) surveillance study-a facility-based diarrhea surveillance study across 7 countries-aims to generate evidence on health system and household costs associated with medically attended diarrhea in children.

Measuring the Effectiveness of COVID-19 Vaccines Used during a Surge of the Delta Variant of SARS-CoV-2 in Bangladesh: A Test-Negative Design Evaluation.

Background: From May to December 2021, Bangladesh experienced a major surge in the Delta variant of SARS-CoV-2. The earlier rollout of several vaccines offered the opportunity to evaluate vaccine effectiveness against this variant.

Methods: A prospective, test-negative case-control study was conducted in five large hospitals in Dhaka between September and December 2021.
