The Korea Disease Control and Prevention Agency sought to ease any vaccine concerns among the public during a briefing Wednesday saying most adverse reactions to COVID-19 vaccines reported overseas in the United States, Britain and elsewhere faded within a few days.
The reported reactions include pain in the injected area, fatigue, headaches and rash.
Health experts also said that other than anaphylaxis, which can be properly treated with early diagnosis, no other critical reactions can be linked to the vaccines.
"No causal link has been reported between the vaccines and facial paralysis and cases of death. And anaphylaxis, a serious allergic reaction which can appear in different ways depending on the person, is rare among those who've been vaccinated."
Officials also addressed public concern surrounding the AstraZeneca vaccine's safety, saying the shots do meet safety and efficacy standards.
"For reference, an interval of 8 to 12 weeks is recommended between doses for the AstraZeneca vaccine. The Pfizer shots will be given with 3 weeks in between."
Recent research published in British medical journal 'The Lancet' showed that AstraZeneca's efficacy rate rises from 55 percent to 81 percent when the dose interval is widened from up to six weeks to three months.
Meanwhile, experts outright rejected rumors of the government planting chips in people through the shots in order to monitor them.
"As a man of science, I think it's a shame that these concerns exist. 'Monitoring people by inserting chips?' As far as I know, that's not even scientifically possible right now."
Professor Choi says that people should not have their judgement clouded by disinformation.
