The World Immunization Week - The Big Catch-Up

The World Immunization Week, celebrated every year in the last week of April, is an opportunity to raise awareness about the importance of vaccination for protecting people of all ages against preventable diseases. This year's theme, "The Big Catch-Up," calls for urgent action to recover lost progress in vaccination coverage caused by the COVID-19 pandemic. Millions of children worldwide have missed out on essential vaccines due to disruptions in routine immunization services, putting them at risk of deadly diseases. 

Immunization is one of the most effective ways to prevent infectious diseases, reducing illness, disability, and death worldwide. Vaccines are safe and effective, and they provide long-lasting protection against a range of infectious diseases, including measles, polio, pneumonia, and cervical cancer. Vaccines not only protect individuals but also contribute to herd immunity, which means that when enough people are vaccinated, the spread of the disease is slowed or stopped altogether. 

Despite the clear benefits of vaccines, millions of children worldwide remain unvaccinated. According to the World Health Organization (WHO), around 20 million children missed out on essential vaccines in 2020, and more than half of them live in just ten countries. This is a significant setback in global efforts to achieve the Sustainable Development Goal of ensuring universal access to immunization by 2030. 

The COVID-19 pandemic has exacerbated the problem of vaccine hesitancy and misinformation, which has led to a decline in vaccination coverage in many countries. Fear of contracting COVID-19 at health facilities, the closure of schools and community centers, and disruptions in the supply chain of vaccines have further hampered efforts to maintain routine immunization services. 

To address these challenges, the WHO has called for urgent action to recover lost progress in vaccination coverage. The Big Catch-Up campaign aims to rally political leaders, health workers, parents, and children to strengthen health systems and roll out vaccinations, ensuring that every child, everywhere, gets a chance to grow up healthier and happier. The campaign emphasizes the need to prioritize vaccination services as an essential health service and to ensure that they are maintained even during crises. 

The Big Catch-Up campaign also highlights the importance of community engagement and the role of parents and caregivers in ensuring that their children receive the recommended vaccines on time. The campaign encourages parents to talk to their healthcare providers, ask questions, and get accurate information about vaccines to make informed decisions about their children's health.

The Big Catch-Up campaign is an opportunity for governments, donors, and partners to invest in health systems and make vaccines more accessible to those who need them the most. The campaign calls for increased funding for immunization programs, the development of new vaccines, and the expansion of vaccination services to hard-to-reach areas. 

The success of the Big Catch-Up campaign depends on the collective action of governments, civil society, and the private sector. Governments must prioritize immunization services as an essential health service and allocate adequate resources to maintain routine immunization services. Civil society organizations and the private sector can play a crucial role in raising awareness about the importance of vaccines and supporting vaccination campaigns. 

In the end, the World Immunization Week and the Big Catch-Up campaign offer a critical opportunity to raise awareness about the importance of vaccines and to take urgent action to recover lost progress in vaccination coverage. Vaccines save lives, and they are a fundamental tool in the fight against infectious diseases. Every child, everywhere, deserves a chance to grow up healthy and happy, and vaccines are essential in making this a reality. As we continue to navigate the COVID-19 pandemic, we must not forget the importance of routine immunization services and the need to ensure that every child has access to life-saving vaccines.
