A groundbreaking study reveals a startling truth: children are more susceptible to heart and inflammatory issues after COVID-19 infection than vaccination. This extensive research, published in The Lancet Child and Adolescent Health, sheds light on the long-term risks associated with COVID-19 in young individuals.
But here's the catch: the study, conducted by researchers from the Universities of Cambridge, Edinburgh, and University College London, analyzed the health records of nearly 14 million children in England, aged under 18, between 2020 and 2022. The findings are eye-opening. During this period, 3.9 million children received a COVID-19 diagnosis, while 3.4 million received the Pfizer–BioNTech vaccine.
The researchers delved into the short- and long-term risks of rare complications, including blood clots, low platelet levels, and inflammation of the heart and its surrounding tissue. They discovered that after a COVID-19 diagnosis, the risks of these conditions were significantly higher in the first four weeks and remained elevated for up to a year compared to children without the infection.
And this is where it gets intriguing: post-vaccination, the team only observed a short-term increased risk of heart inflammation in the initial four weeks, returning to baseline levels after that. In the six-month study period, COVID-19 infection resulted in 2.24 additional cases of heart inflammation per 100,000 children, while vaccination caused only 0.85 extra cases.
Previous studies have indicated that children diagnosed with COVID-19 are at a higher risk of developing these conditions compared to their peers without the infection. However, this new research is the first to directly compare the long-term risks of COVID-19 diagnosis and vaccination in children.
A controversial point to consider: while COVID-19 vaccines have proven effective in preventing severe illness and hospitalization in children, rare cases of heart inflammation have been reported shortly after vaccination, especially with mRNA vaccines. This raises the question: is the risk of infection or vaccination greater for children's heart health?
"The pandemic has presented parents and caregivers with challenging decisions," says co-author Professor Pia Hardelid. "By providing comprehensive data on both infection and vaccination outcomes, we aim to empower families and healthcare professionals to make informed choices."
Co-author Professor Angela Wood adds, "Our study, utilizing electronic health records from all children in England, revealed higher and more persistent risks after COVID-19 infection compared to vaccination. As new variants emerge, the risks associated with infection may evolve, emphasizing the ongoing need for whole-population health data monitoring to inform vaccine strategies."
Professor William Whiteley, another co-author, emphasizes, "Reliable information is crucial for parents, young people, and children to make health decisions. Our study shows that during the pandemic, the risks of heart inflammation were lower after vaccination than after COVID-19 infection."
