NCT04638985

Brief Summary

Eligible,healthy infants who have finished the 3-dose-schedule of sIPV+DTaP combined vaccination clinical trial (NCT04054882) will be recruited and divided into 4 groups, and will receive vaccination at the age of 18-month-old as follows: Group 1: sIPV + DTaP + MMR, Group 2: sIPV only, Group 3: DTaP only, Group 4: MMR only. The immunogenicity and safety of the 4 groups will be compared and analyzed before and 30 days after vaccination.
