Initiatives to increase childhood vaccination coverage: an international comparison

Area of Science:

• Public Health
• Epidemiology
• Health Policy

Background:

• Childhood vaccination coverage often falls below World Health Organization (WHO) recommended levels.
• Fluctuations in vaccination rates pose a significant public health challenge.

Purpose of the Study:

• To survey and categorize interventions implemented by various countries to enhance childhood vaccination rates.
• To assess the reported effects and evidence of effectiveness for these interventions.

Main Methods:

• A structured data collection template was used, completed by country experts from Europe, Israel, the USA, and Canada.
• Data were collected from 22 countries regarding measures introduced between 2014 and 2019.
• Interventions were analyzed based on type, target population, and reported outcomes.

Main Results:

• Four primary intervention types were identified: restrictive measures, financial incentives, logistical support, and promotional campaigns.
• Restrictive measures included mandatory vaccination policies and school access limitations.
• Communication and knowledge enhancement initiatives were common, with some positive effects noted for financial incentives to providers.

Conclusions:

• Most implemented strategies focused on communication and education to improve vaccination coverage.
• There is a notable lack of robust evidence demonstrating the impact of these measures on overall vaccination rates.
