The objective of the study was to measure the Adverse Events Following Immunization (AEFI) 24-72 hours post-vaccination and its effect at three months after vaccination. An online survey was distributed to 1574 subjects who received the first dose, and 530 respondents (response rate 33.6%) who answered the questionnaire were sent the form again for the second dose, and 249 subjects responded (response rate 46.9%). From the first dose: 322 female (60.9%), 207 male (39.1%). There were 22 respondents who had fever on the first day and only five respondents on the second day. In addition, 147 (27.8%) felt pain in the injection site, nausea 30 respondents (5.7%), vomiting six persons, bloating 35 respondents (6.6%), and diarrhea ten respondents (1.9%).
