If a person who has not been vaccinated with the coronavirus vaccine in the past is vaccinated twice (as in the case of special temporary vaccination, as in the case of initial vaccinations)?

For those who have never been vaccinated with the coronavirus vaccine in the past, you can receive the second vaccination after the period specified by the vaccine manufacturer, but it is not mandatory to inoculate twice.
In addition, the number of vaccinations for regular vaccinations is, in principle, only once during the vaccination period.
Please note that if you have received the regular vaccination once during the regular vaccination period and receive the second and subsequent vaccinations, it will be a voluntary vaccination.
In addition, about outside inoculation period of periodical inoculation, all people including person targeted for periodical inoculation become voluntary inoculation regardless of the number of times.
