UK Study Finds COVID-19 Infection Poses Greater Risk to Children Than Vaccination
London, UK – November 21, 2025 – A comprehensive study published in The Lancet Child & Adolescent Health has revealed that children and adolescents who contract COVID-19 face a significantly higher risk of developing heart inflammation, blood clots, and other serious inflammatory conditions compared to those who receive the Pfizer-BioNTech vaccine.
Researchers from the University of Cambridge analyzed the anonymized medical records of nearly 14 million individuals under 18 in England between January 2020 and December 2022. The study, one of the largest of its kind, found that in the weeks and months following infection, children were at a substantially increased risk of conditions such as myocarditis, pericarditis, blood clots, and multisystem inflammatory syndrome (MIS-C).
Specifically, the risk of inflammatory conditions was nearly 15 times higher in the first week following infection compared to uninfected peers. The risk of venous thromboembolism was almost 5 times higher, and cardiac inflammation was 3.5 times higher. While these risks diminished over time, some remained elevated for up to a year after infection.
In contrast, the study found only a small, short-term increase in the risk of myocarditis and pericarditis following vaccination, with the risk peaking in the first week and rapidly declining afterward. There was no observed increase in the risk of blood clots or inflammatory conditions after vaccination.
Researchers calculated that the excess risk of cardiac inflammation was approximately 3 times higher after COVID-19 infection than after vaccination. They emphasized that cases of myocarditis following vaccination were generally mild and resolved quickly.
“Our findings should reassure parents and policymakers weighing the benefits of vaccinating children,” said the study authors. “Children and young people have higher risks of rare vascular and inflammatory diseases up to 12 months after COVID-19 infection and a lower short-term risk after vaccination.”
Public health experts have hailed the study as crucial evidence supporting continued vaccination efforts for children and adolescents. They believe the findings should help alleviate concerns about vaccine safety, particularly given the significantly greater risks associated with COVID-19 infection itself.
The study, supported by the Wellcome Trust, the British Heart Foundation, and Health Data Research UK, reinforces the message that while children often experience mild acute COVID-19, the infection can lead to serious long-term complications. Vaccination, on the other hand, offers a far safer and more effective way to protect children from these risks.
