World Immunisation Week 2023 - 24 - 30 April

World Immunisation Week 2023 is from 24th to 30th April with the theme of “The Big Catch-up.” This week provides an opportunity to highlight the importance of immunisation in protecting individuals and communities against vaccine preventable diseases.

The campaign "The Big Catch-up" is crucial as it arrives at a pivotal moment for immunisation. The COVID-19 pandemic has had a significant impact on global immunisation efforts, resulting in a backlog of missed vaccinations worldwide. Therefore, it is imperative to address this issue by improving immunisation services, closing the gap and reaching out to millions of individuals who have been deprived of the life-saving benefits of vaccines.

The World Health Organisation (WHO) 2023 campaign aims to address this backlog and promote global effort to vaccinate millions of children and restore vaccination levels to pre-pandemic standards.
