Aluminum in childhood vaccines has long been the cause of speculation about a potential link to allergies and asthma, but a new study designed to figure out whether there might be a connection did not come to a definitive conclusion.
While the federally funded study found a possible link, experts noted the research has important shortcomings.
And the lifesaving benefits of vaccines are still likely to outweigh the asthma risk, even if researchers confirm a link later, lead study author Dr. Matthew Daley, an associate professor of pediatrics at the University of Colorado School of Medicine, in Aurora, told the Associated Press.
