Understanding World Immunization Week
A Historical Perspective on Immunization
World Immunization Week has been an annual observance since 1974, designed to showcase the enormous potential of vaccines in preventing outbreaks and saving lives worldwide. Initially focusing on just six key childhood vaccines, the initiative now promotes a total of thirteen vaccines that cater to people of all ages. Over the decades, community immunity efforts have proven extremely successful, preventing millions of deaths and illnesses as vaccines have saved at least 154 million lives globally.
The Current Landscape of Vaccination
Despite these achievements, we face critical setbacks. The COVID-19 pandemic significantly hampered vaccination efforts, putting millions of children’s lives at risk. With the challenges posed by the pandemic, there remains a glaring need to ensure that every child is vaccinated, particularly in regions like South-East Asia where significant portions of the population remain unprotected.

Why Vaccination Matters
The Economic and Social Impact of Vaccines
- For every dollar invested in immunization, thereโs an impressive return of USD 54.
- Vaccination strengthens health systems by linking children to vital services, including basic healthcare and nutrition.
- Diseases like measles and diphtheria are on the rise, threatening to undo decades of progress in child health.

Challenges and Concerns in the Vaccination Landscape
Collective Action Required
Leading health authorities, including Saima Wazed of the WHO and organizations like UNICEF and Gavi, have raised alarms about the urgent need for collaborative action. In South-East Asia, over two million infants remain completely unvaccinated, highlighting a severe gap that must be addressed post-pandemic.
The Economic Burden of Outbreaks
Outbreaks of vaccine-preventable diseases impose significant financial burdens on healthcare systems and devastate communities. Economic losses arise not only from direct healthcare expenditure but also from lost productivity, as people are forced to take time off work due to illness. Simultaneously, the propagation of misinformation further complicates efforts to maintain public trust and achieve herd immunity.
