[QUOTE="Jeanne - Simme Valley, post: 1471848, member: 968"] Quote from article: "The virus is contracted from contact with infected cattle, it is also readily sexually transmitted. Those [b][u]animals infected as adults usually recover from the virus and become immune.[/u][/b] BVDV is however readily transmitted across the placenta from cow to calf. Animals that are infected in-utero are born permanently (persistently) infected with the virus. These animals excrete large volumes of virus all of their lives and are the main route of infections in other animals. Identifying and removing these animals is the mainstay of eradication schemes for the BVDV. It needs only one persistently infected animal to be introduced into a susceptible herd to cause very significant financial losses" So, the article you posted says the cow usually recovers & becomes immune. Yes, MLV can be unsafe if not timed properly. But, if you read the article comparing the MLV vs killed - the list of PROS for the MLV sure outweigh the Killed. Same reasons I use it, longer protection, better protection - and cheaper. [/QUOTE]
