New corona vaccine 5th start at large-scale vaccination venue Tokyo
Since the interval between vaccinations for the new coronavirus has been shortened to at least three months, the fifth vaccination, which is the largest number, will be possible from 21 October 2022, and additional vaccinations are desired at large-scale vaccination venues in Tokyo.
Regarding the third and subsequent booster vaccinations for the Omicron strain of the new coronavirus, the Ministry of Health, Labor and Welfare has decided to shorten the interval from the previous vaccination, which was at least five months, to three months.
In response to this, those who were vaccinated in July this year will be able to receive additional vaccinations from the 21st, and the number of people who visited the North Observatory of the Tokyo Metropolitan Government Office, one of the large-scale vaccination venues in the city, is increasing.
The fifth vaccination, which is the largest number, will be possible, and from the 25th of next week, reservations can be made on a dedicated website.
Kenichiro Nakajo, Director of New Coronavirus Vaccines in Tokyo, said, "Since there is concern about simultaneous epidemics with influenza, I would like you to consider vaccination on this occasion when the vaccination interval is shortened."
