BCG Vaccination and COVID-19 Risk in Cape Verde Healthcare Workers, 2021

A case-control study of 465 healthcare workers in Cape Verde in 2021, examining the association between lifetime BCG vaccination and SARS-CoV-2 infection risk. The dataset includes 215 cases and 250 controls, with sociodemographic, epidemiological, and employment variables. It was published on figshare under a CC-BY-4.0 license.

Use Cases

• Assessing the association between BCG vaccination and COVID-19 infection based on case-control status.
• Analyzing the impact of sociodemographic factors on infection risk among healthcare workers.
• Studying the relationship between COVID-19 vaccination completion and infection odds in a specific population.
• Investigating the prevalence of persistent symptoms and hospitalization rates post-COVID-19 in a healthcare worker cohort.

Strengths

• Dataset size is explicitly stated with 215 cases and 250 controls.
• Study design is clearly described as a case-control study conducted in 2021.
• Primary exposure (BCG vaccination status) and outcome (SARS-CoV-2 infection) are well-defined.
• Analysis employed a maximum likelihood forward selection logistic regression model.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown for the underlying data file, which may limit suitability assessment.
• Data is limited to healthcare workers from three hospitals on two islands in Cape Verde, which may affect generalizability.
