Universal versus risk-based strategies for vaccinating children against COVID-19: Japan and Korea.

The global impact of COVID-19 on children emphasises the need for effective vaccination. While most cases are mild, those with underlying conditions face severe risks. Public health agencies promote various paediatric vaccination approaches. Japan universally recommends vaccination, while Korea prioritises high-risk children. Despite similar healthcare systems, Japan's coverage rates (19%-72%) surpass Korea's (2%-55%). Korea's child death rates are higher, indicating increased risk. Both lack methods to address individual risks, hindering prevention. This study advocates universal vaccination to mitigate future pandemics' impact on children systematically.
