Disclosed herein, in certain embodiments, are recombinant myxoma viruses (MYXVs) and nucleic acid constructs encoding the recombinant MYXVs. In some embodiments, the MYXVs are engineered to inactivate or attenuate an activity or expression level of an M153 protein. In some embodiments, the MYXVs are engineered to express one or more transgenes such as a tumor necrosis factor (TNF), interleukin-12 (IL-12), or decorin. Also disclosed herein, in certain embodiments, are methods of using the MYXVs. Some embodiments include providing a MYXV as described herein to a subject in need thereof.

The present application relates to method of vaccinating a subject against infection by an enveloped virus. The method includes providing a compound of the Formula (I) as described herein, and contacting the compound of Formula (I) with an isolated enveloped virus, having a membrane, to inactivate the membrane of the isolated enveloped virus. The subject is then treated with the enveloped virus having an inactivated membrane to vaccinate the subject against the enveloped virus. Further disclosed is an ex vivo vaccine composition including the compound of Formula (I) and an enveloped virus.
