STATUS OF REACTIONS AFTER VACCINATION WITH SII AND BOPV VACCINES IN CHILDREN UNDER 1 YEAR OLD IN THE EXPANDED IMMUNIZATION PROGRAM IN NINH BINH PROVINCE IN 2021

Abstract

bOPV and SII vaccines are two commonly used vaccines in the expanded immunization program. Therefore, the follow-up of side effects after injection is an important work to understand the causes and factors related to this condition. Design a cross-sectional descriptive study on 350 children under 1 year old vaccinated with SII and bOPV vaccines in the expanded immunization program at health stations in Ninh Binh province. The results after vaccination with SII and bOPV accounted for a high rate with 93,71%. In which, local reactions after injection accounted for 56%, systemic reactions after injection accounted for 86%. The most common reactions were fever with 82,57%, mild irritability 40%, pain at the injection site 32% and swelling at the injection site 25,71%. The analysis results show that there is a relationship between the nutritional status of children when vaccinated and the times of vaccine use to the post-injection response rate with OR of 0,01 (0,00 – 0,41) and 0,08 (0,01 – 0,80) respectively with statistical significance p<0,05. Parents/caregivers should be extra cautious after their child's first dose of SII and bOPV vaccines.
