Recent trends in vaccine coverage and confidence: A cause for concern

Area of Science:

• Public Health
• Epidemiology
• Health Behavior

Background:

• Routine childhood immunization coverage has reached a decades-long low.
• Declining vaccine confidence, particularly among young adults, presents a significant public health concern.
• This trend has potential long-term implications for infectious disease control.

Purpose of the Study:

• To examine global trends and levels of vaccine confidence over time.
• To identify key drivers influencing vaccine confidence.
• To assess the impact of the COVID-19 pandemic on vaccine confidence.

Main Methods:

• Analysis of global data on vaccine confidence trends.
• Exploration of factors affecting vaccine acceptance.

Main Results:

• Significant declines in vaccine confidence observed globally.
• Young adults show pronounced decreases in confidence.
• The COVID-19 pandemic has demonstrably influenced current vaccine confidence levels.

Conclusions:

• Understanding the drivers of waning vaccine confidence is crucial.
• Critical evaluation of pandemic response measures is needed.
• Mitigating losses in vaccine confidence and uptake is vital for future health resilience.
