[Moon Young-sook/55 years old, moderna vaccinated person: When I made a reservation, I also waited without sleeping since 12:00 in the morning. After getting it, I feel relieved.]

However, it is not easy to get Moderna vaccine right away.

[Park Ji-young / Head of Vaccine Introduction Support Team, Central Accident Remediation Headquarters: Moderna has been notified that there is an issue related to production. The (inoculation) schedule may be adjusted in some cases like Moderna.]

Of the 40 million doses of Moderna vaccine the government has purchased, only 1.15 million doses have been introduced so far.

Due to the delay in the introduction of the Moderna vaccine, the quarantine authorities changed to the Pfizer vaccine only for those vaccinated in the metropolitan area this week, and had them all receive Pfizer next week.

Hospitals and clinics that only vaccinate Moderna are an exception.

100,000 people aged 60 to 74 who changed or canceled reservations also started getting vaccinated yesterday, but Moderna changed to Pfizer's parallel vaccination.

Worksites with affiliated lawmakers start vaccination today, education and care workers tomorrow, and high school students other than high school entrance exams start on the 10th of next month, and they all get the Pfizer vaccine.

Meanwhile, for the first time, the government recognized the causality of vaccines and cases of deaths due to myocarditis after vaccination.
