Does PHF-W help only high-risk infants with a family history of allergy?
Although some studies suggest a protective effect in all infants (with or without a family history), the strongest evidence applies to those infants who come from families with a history of allergy. As is standard in most clinical trials, the studies were conducted in populations identified as “high-risk” (in this case, healthy infants with family history of allergy) in order to effectively assess the allergy-prevention effect by comparing results from an identifiable patient population.
