Purpose
This study investigated the factors associated with Adverse Event Following Immunization (AEFI) for Coronavirus Disease 2019 (COVID-19) in selected areas in Indonesia.
Methods
We used a cross-sectional approach with a correlational research design; a total of 2,730 samples were collected using accidental sampling. The instrument was an online questionnaire. The AEFI questionnaire was a modified version of the survey instrument of the Ministry of Health, Republic of Indonesia. χ² and Fisher's exact tests were used for statistical analysis.
Results
The most common AEFI were pain at the injection site (81.2%), drowsiness (77.2%), hunger (77.0%), headache (70.3%), and weakness (58.4%). Bivariate testing revealed that gender, age, disease history, vaccine type, and anxiety had statistically significant relationships with the incidence of weakness, pain at the injection site, and headache (p<.050). Age and vaccine type were significantly related to the incidence of fever, swelling at the injection site, and hunger. Gender, vaccine type, and anxiety were found to have statistically significant relationships with the incidence of nausea. Vaccine type and anxiety were significantly related to vomiting.
Conclusion
The study found that gender, age, history of disease, vaccine type, and level of anxiety were associated with several adverse events following COVID-19 immunization. These findings provide data to nurses and other health workers to help them offer additional interventions to prevent or reduce adverse events in at-risk groups following COVID-19 vaccination.

PURPOSE
The purpose of this study is to identify health beliefs and knowledge related to hepatitis A vaccination (HAV). Preventative behaviors related to HAV were also examined.
METHODS
The convenience sample of 332 students were drawn from a university in Chung-nam province. The results were analyzed using descriptive statistics, t-test, ANOVA, Scheffetest, Pearson's correlation coefficient, and stepwise multiple regression with SPSS for Windows 21.0 software.
RESULTS
Vaccination rates for hepatitis A were 23.4%. The mean scores of health beliefs, knowledge and preventative behaviors related to hepatitis A were 2.38+/-0.25, 0.34+/-0.30, and 3.15+/-0.40 respectively. The factors found to be related to hepatitis A preventative behaviors were HAV, having the HAV antibody and health beliefs.
CONCLUSION
An experience of HAV, having HAV antibody, and positive health beliefs related to hepatitis A may be necessary to increase voluntary hepatitis A preventive behaviors among university students. It is essential to develop the strategy of educating university students about HAV and having HAV antibody as well as reinforcing health beliefs about hepatitis A which prevent the hepatitis A occurrence.
