According to a paper by Dr. Anna Yousaf of the U.S. Centers for Disease Control and Prevention published in the Journal of the American Medical Association (JAMA Network Open) on the 25th, a case-control study of 600 vaccinated and unvaccinated people aged 5 to 17 found that mRNA vaccination reduced the probability of developing one or two symptoms of COVID-19 by 57 to 73%.
From July 2021 to September 2022, 622 people, including 474 (76%) children with the COVID-19 mRNA vaccine and 148 (24%) unvaccinated children enrolled in a number of medical institutions, were followed up until May 2023 for the probability of developing the aftereffects of COVID-19 infection and treatment, and 28 people (4.5%) were infected with the aftereffects of COVID-19 during the follow-up period.
Among those who were vaccinated, 16 (57%) were infected with the aftereffects of COVID-19, and 458 (77%) were not infected with the aftereffects.
As a result of comparing the probability of developing aftereffects considering demographic characteristics, the number of acute COVID-19 symptoms, and underlying health conditions, vaccinated children were 57% less likely to show more than one symptom than unvaccinated children, and 73% less likely to show more than two symptoms.
The research team pointed out that the aftereffects of COVID-19 can cause prolonged symptoms and mental and physical weakness, hindering not only health but also studies, and said it shows that COVID-19 mRNA vaccination reduces children's chances of COVID-19 aftereffects by 57-73% and reduces their chances of functional decline by 75%.
