Currently, there is no therapeutic or preventive vaccine for HSV2 infection that has been approved for marketing, but basically all of them are in the early research stage or clinical trial stage. 1. Therapeutic vaccine: It can remove HSV-1/2 virus from the body through gene editing technology, and is used to alleviate the symptoms and infectiousness of people who have already been infected with HSV-2 (HSV-2 seropositive), and there is already a therapeutic vaccine for HSV2 in clinical trials. 2. Prophylactic vaccines: used to prevent people who have not yet been infected (HSV-2 seronegative) from being infected with HSV-2. Depending on the type, they can be categorized into inactivated vaccines, live attenuated vaccines, replication-deficient vaccines, recombinant subunit vaccines, synthetic peptide vaccines, DNA vaccines, mRNA vaccines, and so on.
