No damage evident in immune system
In the 21st century, children received a greater number of vaccinations than those in past generations, leading to fear and speculation of an increased risk of infection.
Researchers, however, are now willing to dispel any such concerns.
“It’s understandable that parents across the US have questions and concerns about vaccine safety,” said co-author Matthew Daley, a Kaiser Permanente pediatrician. “This latest study found that vaccination didn’t appear to damage the immune system in a way that made kids more infection-prone. This finding will hopefully provide additional reassurance to parents about the safety of the recommended schedule.”
Dr. Daley is referring to a recent report in the Journal of the American Medical Association that investigates a link between the proposed vaccination schedule and the rate of illnesses and infection among American children.
A group of almost 200 children diagnosed with respiratory and gastrointestinal illnesses was compared to another group of 750 children with no such diagnoses in the first two years of life. The conclusion was “not associated with any increased risk of infections not targeted by vaccines over the next 24 months of life.”
“This new study suggests the theory of overloading an infant’s immune system is highly unlikely,” said lead author Jason Glanz, senior investigator at the Kaiser Permanente Colorado Institute for Health Research.
