Vaccination is essential in preventing infectious diseases, particularly in pediatric populations. However, optimizing vaccine efficacy while minimizing post-vaccination complications in children remains a significant challenge due to the developmental state of their immune systems. This article reviews current strategies for enhancing vaccine effectiveness, including the use of adjuvants, improved vaccine formulations, and personalized vaccination schedules. Additionally, it explores methods to reduce post-vaccination complications, such as pre-vaccination screening, prophylactic treatments, and minimizing antigen load. These approaches aim to provide better protection for children while ensuring safety and reducing adverse effects. The findings highlight the need for continued research into vaccine optimization tailored to pediatric needs, particularly in the era of advanced vaccine technologies.
