Discovery of a potential new target for new MPOX or broad pox vaccines

In a recent study posted to the medRxiv* preprint server, researchers in the United Kingdom developed a pooled enzyme-linked immunosorbent (ELISA) assay using mpox (MPX) virus (MPXV) antigens and vaccinia virus (VACV) antigens. They also assessed humoral responses to and identification of antigens of MPXV IIa clade and IIb clade, in comparison to recipients of smallpox vaccines (ACAM2000 and IMVANEX).
