A productive infection by vaccinia virus involves entry into the cell; expression and replication of the genome; defense against specific and non-specific host immune mechanisms; and assembly and release of infectious, enveloped, virus particles. Many of these steps involve interactions of viral proteins with cellular proteins or membranes. Combined genetic, biochemical, and electron microscopic approaches are being used to investigate these complex processes. During the past year, emphasis has been on understanding the steps in the formation and transmission of intracellular and extracellular virions, the host range restriction of poxviruses, and viral immune defense proteins.

痘苗病毒的有效感染涉及进入细胞；基因组的表达和复制；防御特定和非特定的宿主免疫机制；以及感染性、有包膜的病毒颗粒的组装和释放。其中许多步骤涉及病毒蛋白与细胞蛋白或细胞膜的相互作用。遗传、生化和电子显微镜相结合的方法被用来研究这些复杂的过程。在过去的一年里，重点是了解细胞内和细胞外病毒颗粒的形成和传播步骤、痘病毒的宿主范围限制和病毒免疫防御蛋白。
