Empox (monkeypox) vaccine “More than 70% of vaccinations have sufficient antibodies”. As of the 8th of this month, there have been a total of 242 Empox patients in Japan.

"Additional vaccinations may be necessary in order to maintain the antibodies that decrease over time," says Professor Shigeru Morikawa.
