Seroconversion was defined as a pre-vaccination haemagglutinin inhibition (HI) titer \<1:10 and post-vaccination HI titer ≥1:40 or as a pre-vaccination HI titer ≥1:10 and at minimum four-fold rise in post-vaccination antibody titer |

Participant flow
Recruitment details
The study was conducted in 13 centers across 4 countries: Mexico, Colombia, Panama and Philippines.
Pre-assignment details
Due to GCP non-compliance at the Mexico site, data of 312 subjects (3-8 year olds) enrolled from this site were excluded from the final immunogenicity and safety analysis. The population was analyzed in the enrolled set.

| TIV (3-8 Years) The group consisted of naive (who have never received influenza vaccination or had received only one influenza vaccine dose in the same season) and non-naive subjects (who had a record of previous influenza vaccination).

| Control (3-8 Years) The group \[control (4-8 years) + control (3 to\<4 years)\] consisted of naive (who have never received influenza vaccination or had received only one influenza vaccine dose in the same season) and non-naive subjects (who had a record of previous influenza vaccination). Subjects (4-\<9 years) received TIVf and subjects (3-\<4 years) received comparator TIV. The non-naive subjects received one dose and naive subjects received two doses of vaccine. | 533 |
