Viral particles released after human cytomegalovirus infection

摘要

This invention relates to viral particles which are released by mammal cells after the infection with human cytomegalovirus (HCMV). The invention also relates to particles whose antigenicity has been optimized by changing the HCMV using genetic engineering. The invention further relates to the use of such particles as a vaccine and a method for multiplying the HCMV in mammal cells.
