Better understanding of the burden of influenza in healthy children regarding hospitalization rates, outpatient medical visits, community-managed illness and socioeconomic impact on families and society exists; this has potential implications for universal vaccination policies under consideration.
Both the burden of influenza in childhood morbidity and its social impact are substantial. There is considerable room for improvement in both the prevention and early recognition (trigger treatment with antivirals) of influenza. Our data will inform decisions regarding the value of a universal influenza vaccine programme.
This study demonstrated the feasibility and utility of parent-collected and mailed respiratory specimens for VE research in the childcare setting. Two-thirds of parent-collected swabs proved positive for at least one virus. Finding ways to reduce reluctance of parents to submit samples could improve the representativeness of samples collected and the power of the study. No evidence was found for influenza VE, but point estimates were in the direction of protection.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
