Similar protective effects found for different forms of influenza vaccines
Similar protective effects found for different forms of influenza vaccines. Immunizing children and teens with live attenuated influenza vaccine (LAIV) or inactivated influenza vaccine (IIV) brings similar protection for children and members of their community. In 48 rural Canadian Hutterite colonies, children 36 months to 15 years of age received either intranasal LAIV or injectable IIV. Over three years, the number of related antimicrobial prescriptions, medical visits for respiratory illness, hospitalizations, or absenteeism from school or work did not differ. Only 22 hospitalizations occurred—11 for each vaccine. Given the similar outcomes for LAIV and IIV, inactivated vaccines like IIV “that are available at a lower cost seem to be cost-effective,” the authors write in an article published online on August 16 in the Annals of Internal Medicine.Copyright © 2016 Wolters Kluwer Health, Inc.
