Evaluating the long-term safety and effectiveness of the Dengvaxia vaccine in children in the Philippines
Long-term safety and effectiveness of Dengvaxia in the Philippines
This study is looking at how safe and effective the Dengvaxia vaccine is for children in the Philippines, especially those who may not have had dengue before getting the shot, to help us understand how well it works and any risks involved.

What this research studies
This research investigates the long-term safety and effectiveness of the Dengvaxia vaccine, which was administered to over 830,000 children in the Philippines without prior testing for dengue virus exposure. The study aims to understand the immune responses, including antibody and T-cell responses, in children who received the vaccine, particularly focusing on those who may have been seronegative at the time of vaccination. By analyzing real-world data and responses to dengue infections, the research seeks to fill critical knowledge gaps regarding the vaccine's performance and associated risks. The findings could help inform future vaccination strategies and guidelines.
Who could benefit from this research
Good fit: Ideal candidates for this research are children aged 0-11 years who received the Dengvaxia vaccine in the Philippines.
Not a fit: Patients who have not received the Dengvaxia vaccine or are outside the age range of 0-11 years may not benefit from this research.
Why it matters
Potential benefit: If successful, this research could lead to improved vaccination strategies that enhance safety and effectiveness for children at risk of severe dengue disease.
How similar studies have performed: Previous studies have indicated challenges with the Dengvaxia vaccine, particularly among seronegative recipients, highlighting the need for this investigation.
