Abstract

Objectives: Describe the knowledge and practice on COVID-19 vaccine post-vaccination response
and identify some factors related to parents’ knowledge and practice about COVID-19 vaccine postvaccination response at Quang Trung Secondary School, Vinh City in 2022.
Subjects and research methods: A cross-sectional descriptive study with an analysis of 351 parents
whose children at Quang Trung Secondary School have been vaccinated against COVID-19 since
May. 2/2021-5/2021.
Results: 49% of the respondents had good knowledge of the COVID-19 vaccine post-vaccination
response. The rate of the study subjects who recognized common signs of reaction after vaccination
with the COVID-19 vaccine was a low-grade fever of ≤ 38.5ºC, accounting for 83.5%. The percentage
of study subjects who recognized abnormal signs after vaccination against COVID-19 was a very
high fever of ≥ 40ºC; chest tightness, trouble breathing; convulsions had the same rate, respectively
78.6%; 73.8% and 72.9%; signs of generalized swelling had the lowest rate (51.9%). The rate of
research participants who practiced monitoring for 30 minutes at the vaccination site and practiced
monitoring for at least 24 hours at home was 95.4%. The sign of reactions after vaccination was a
general condition (69.8%) and the least was rash (31.3%). Some factors such as education level,
occupation, and information sources are related to the knowledge and practice of research subjects
on response to COVID-19 vaccination.
Conclusion: 49% of the respondents had good knowledge of the COVID-19 vaccine post-vaccination
response. 60.4% of study subjects had good practice in response to COVID-19 vaccination. There is
a relationship between education level, occupation, sources of information, knowledge, and practice
of research subjects in response to COVID-19 vaccination.
