The antibody of influenza A H1N1 viruses was 31.47% in the infants who experience two circulations in 3-4 months and 10-11 months old and was 26.42% which only experience circulation in the 5-6 months old. There were no significant difference between 2 groups (chi2 = 1.207, P > 0.05).CONCLUSION:
The group of 13 months age of infants were rarely infected influenza virus in the first time exposure at the age of < or =4 months due to maternal antibodies protection.
