Anne Pham-Huy and Antonella Pucci from Immunize Canada discuss the impact of the COVID-19 pandemic on routine vaccinations for children
The COVID-19 pandemic profoundly affected every aspect of daily life, including routine childhood vaccinations. Immunize Canada recognizes the importance of addressing concerns and providing insights into how the pandemic has influenced childhood immunization practices, its implications on public health, strategies to tackle vaccine hesitancy among parents, and the ground-breaking advancements in vaccine development that emerged during this crisis.
The COVID-19 pandemic disrupted health systems worldwide, leading to widespread interruptions and gaps in routine immunization services for children. Lockdown measures, fear of contracting the virus, and strained health resources resulted in missed or delayed vaccinations for many children. Routine visits to health providers declined significantly, leading to a backlog of missed vaccinations. The closure of schools, which often serve as vaccination centres, further exacerbated the issue. Consequently, a substantial number of children fell behind on their vaccination schedules, leaving them vulnerable to preventable diseases.
The repercussions of missed or delayed childhood vaccinations extend beyond individual health outcomes to affect public health on a broader scale. Vaccination rates serve as a critical measure of community immunity (also known as herd immunity). When vaccination rates decline, the risk of outbreaks and resurgence of vaccine-preventable diseases rises. Diseases such as measles, pertussis, and polio, which were once under control, may resurface and spread rapidly among unvaccinated/ under-vaccinated populations. This not only poses a threat to the health of children but also places a burden on health systems already grappling with the demands of the pandemic.
Vaccine hesitancy
Vaccine hesitancy, fueled by misinformation, disinformation and distrust in vaccines, presents a significant challenge to public health efforts. To address this issue, it is essential to engage in transparent and clear communication, provide evidence-based information, encourage and develop community-led strategies and address concerns with empathy and understanding. Healthcare providers play a crucial role in building trust and providing accurate information about the safety and efficacy of vaccines. Tailored educational campaigns aimed at dispelling myths and addressing common misconceptions can help alleviate vaccine hesitancy. Fostering partnerships with community leaders and leveraging social media platforms to disseminate accurate information can further enhance vaccine acceptance and uptake. Communication and collaborations between specific communities and healthcare providers should be sought to better understand the barriers to vaccination and also optimize access.
The development of COVID-19 vaccines marked a monumental achievement in scientific innovation and collaboration. The unprecedented speed at which vaccines were developed underscores the power of investment in research, technology, and global cooperation during times of crisis. The mRNA vaccine technology demonstrated remarkable efficacy and safety profiles. This breakthrough has paved the way for potential applications in vaccine development for other infectious diseases, including influenza, HIV, and Zika virus, to name a few. The mRNA platform offers advantages such as rapid development, scalability, and versatility, making it a promising tool in the fight against emerging infectious threats.
Safeguarding public health for future generations
The COVID-19 pandemic has had far-reaching implications for childhood vaccinations, underscoring the importance of maintaining immunization services amid crises. Addressing missed or delayed immunizations, combating vaccine hesitancy, and leveraging lessons from COVID-19 vaccine development are crucial steps in safeguarding public health and ensuring a resilient health system for future generations. Immunize Canada remains committed to advocating for vaccination as a cornerstone of disease prevention and control, working towards a healthier and more resilient society.
