About the occurrence of vaccination cases 5 months before the third vaccination in COVID-19 vaccination

The fourth vaccination coupons has been sent to the national vaccination record system (VRS) based on the date of the third vaccination record registered by medical institutions.
When we sent out the 4th vaccination coupons COVID-19 vaccine on May 20, citizens contacted us about the 3rd vaccination date, and as a result of confirming the situation in Motoichi, it was found that there was a case where the third vaccination date of the vaccination record system (VRS) was different from the actual vaccination date.
As soon as it was found, Motoichi alerted the relevant person immediately, but five citizens were inoculated before five months passed since the third vaccination.
