Researchers from Oakland, Calif.-based Kaiser Permanente studied the association between multiple vaccinations and risk of developing non-vaccine targeted infections among U.S. infants. They published their findings in the Journal of the American Medical Association.
Researchers examined a random sample of 193 children diagnosed with a non-vaccine targeted infection. They compared that group to a control group of 751 children who had not been diagnosed with those infections. They studied the infants, newborns to infants aged 47 months, over a one-year period.
The study shows infants who receive multiple vaccines per the routine vaccination schedule have a low risk of developing other infections not targeted by those vaccines in the two years following vaccination.
"This latest study found that vaccination didn't appear to damage the immune system in a way that made kids more infection-prone," said Matthew F. Daley, MD, a study co-author, pediatrician at Kaiser Permanente and researcher at Kaiser Permanente Colorado Institute for Health Research in Aurora.
