COVID-19 Vaccination Impact on Polish Healthcare Professionals, 2021-2022

Polish healthcare professionals participated in a survey from November 2021 to February 2022, with 813 respondents. The data was collected by Karolina Hoffmann to determine the impact of vaccine type and dose number on COVID-19 infection course. It includes results on infection rates, disease severity, and hospitalization differences between vaccinated and unvaccinated groups.

Use Cases

• Analyze the relationship between vaccine dose number and COVID-19 infection occurrence based on the survey results.
• Compare hospitalization rates for COVID 19 between vaccinated and unvaccinated healthcare workers based on the reported percentages.
• Assess the severity of COVID-19 symptoms among individuals with different vaccination statuses based on the mild vs. severe case data.

Strengths

• Survey includes 813 respondents, with specific gender breakdown of 625 women and 188 men.
• Results include statistically significant findings, such as a hospitalization rate of 2.86% for vaccinated vs. 30.76% for unvaccinated subjects (p < 0.0001).
• Clear temporal coverage from November 2021 to February 2022.

Limitations

• Row count is unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
