Persistence of Immune Response After Vaccination With Influenza Vaccine

Status Completed

Clinical Trial Summary

This clinical study will be performed in subjects aged 12-60 years old enrolled in NCT01310374 who received 2010 seasonal influenza vaccine to evaluate the persistence of the immune response of influenza vaccine up to 24 months after vaccination.

Clinical Trial Description

Subjects were previously vaccinated at 12 to 60 years of age with 2010 seasonal influenza vaccine.The persistence phase starts 24 months after the primary vaccination and blood samples will be taken at 6, 12, 18 and 24 months after primary vaccination. Subjects whose antibody titer less than 1:40 at 6 months after primary vaccination will receive a booster dose of influenza vaccine. ;
