Vaccine confidence is higher in more religious countries

Area of Science:

• Global Health
• Sociology of Religion
• Vaccinology

Background:

• Vaccine hesitancy poses a significant global health risk.
• There is considerable international variation in public confidence in vaccines.
• Factors driving these differences in vaccine confidence remain largely unexplored.

Purpose of the Study:

• To investigate the relationship between national religiosity and vaccine confidence.
• To determine if religiosity explains variations in vaccine confidence across countries.

Main Methods:

• Analysis of publicly available cross-national data from 147 countries.
• Statistical correlation between country-level religiosity measures and vaccine confidence indicators.
• Controlling for human development indicators (education, economic development, health).

Main Results:

• A strong positive correlation was found between national religiosity and vaccine confidence.
• Higher religiosity was associated with greater confidence in vaccine safety, importance, and effectiveness.
• This association remained significant after accounting for human development factors.

Conclusions:

• Religiosity appears to be a significant factor associated with higher vaccine confidence globally.
• Understanding the role of religious beliefs is crucial for addressing vaccine hesitancy.
• Further research is needed to elucidate the specific mechanisms underlying this association.
