Official title

Influenza Vaccines: Mix and Match of Trivalent Inactivated Influenza (TIV) and Live Attenuated Influenza Vaccine (LAIV), a Phase I Safety, Immunogenicity, and Viral Shedding Study

Brief summary

Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.

The purpose of this research is to compare the safety and ability to stimulate antibodies (part of the bodies proteins that fight infections) of two influenza (flu) vaccines given to children 12 to 35 months old. The two flu vaccines being compared are: trivalent inactivated influenza virus vaccine (TIV), a killed virus vaccine given as a shot licensed for use in children 6 months of age or older and live attenuated influenza vaccine (LAIV), a live (but weakened) virus vaccine licensed for children 5 years old and older given as a nose spray. The strains of the viruses have been weakened so that they do not cause typical influenza illness, but may allow the body to develop protection against the flu. LAIV vaccine is not licensed for children less than five years of age, therefore its use in this study is investigational. Participation is approximately 7 months in duration.
