Vaccines are among the most powerful public health tools, preventing widespread diseases like measles and polio. A landmark study published in ‘The Lancet’ estimates that global immunization efforts have saved at least 154 million lives over the past 50 years, equating to six lives saved every minute of every year.
This transformative impact is evident in the eradication of smallpox and the near elimination of polio, with cases reduced by more than 99% since the launch of the Global Polio Eradication Initiative in 1988, showcasing the immense power of vaccines in protecting global health.
World Immunization Week 2025 aims to ensure access to vaccines for everyone, especially those in underserved regions. Global health organisations like the World Health Organization (WHO) and the United Nations Children's Fund (UNICEF) emphasize that increasing immunisation coverage is essential to protect vulnerable populations and prevent the resurgence of preventable diseases.
