Changes in hepatitis B vaccine perception in response to the COVID-19 pandemic: Development of the Shift in vaccine confidence (SVC) survey tool.

The COVID-19 pandemic has disrupted access to, adherence to, and perceptions of routine vaccinations. We developed the Shift in Vaccine Confidence (SVC) survey tool to assess the impact of the pandemic on routine vaccinations, with a focus on the HBV vaccine, in Kinshasa, Democratic Republic of Congo (DRC). This study describes the content validation steps we conducted to ensure the survey tool is meaningful to measure changes in vaccine confidence to regular immunization (HBV vaccine) due to the pandemic. Three rounds of stakeholder feedback from a DRC-based study team, content and measurement experts, and study participants allowed us to produce a measure with improved readability and clarity.
