Data was collected by The Vaccine Confidence Project and was published by UNICEF on 20 April 2023.

Vaccine confidence declined in South Korea, Japan, Ghana, Senegal and Papua New Guinea.

The major causes for declining vaccine confidence are misleading information and declining trust in vaccine efficiency.

This decline comes as a backdrop as the world sustained the biggest backslide in childhood immunization in the last 30 years.

A report said that a total of 67 million children missed out on vaccinations between 2019 to 2021, with vaccine coverage levels declining in 112 nations.
