    Figure: Compared to the previously observed monkeypox virus (mpxv-cb), the 2022 monkeypox virus (mpxv-2022) does not contain any new mutations


    Since a new type of monkeypox virus infection was detected in humans in May 2022, more than 52,000 cases have been confirmed in more than 90 countries and territories, and Hong Kong recorded its first imported case


    In the past, VACV-based vaccines were mainly divided into three types


    This year's outbreak of the MMXV-2022 virus carries different genetic variants that have the potential to affect vaccine-induced immune recognition


    Professor MCKAY is also an Adjunct Professor at


    Using genomic and immunological data, the team assessed genetic similarities and differences between VACV and MPXV-2022, particularly in the region


    Professor McKay said: "While we have found small amounts of different mutations in MPXV-2022 with potential immunological effects, our study more broadly shows that VACV and MMXV-2022 are highly similar


    Professor Quadeer said the findings were reassuring


    The World Health Organization recommends a primary preventive vaccine against the neo-monkeypox virus for individuals at high risk of exposure, also known as pre-exposure prophylaxis
