"On the other hand it may happen very seldom or not ever with the measles and mumps vaccine viruses." Quoted from your link IB Humans. This paper refers to instances of secondary infection through live vaccine passed through the vaccinated subject. No reference is made to the vaccinated host being infected by the live vaccine. In the second study you link us to, only three of a sample of eight subjects had live vaccine in their droppings as far as I can make out.
"However, it is possible that differences in the murine and human immune systems result in different temporal requirements for the priming of the immune system." Quoted from your link to the mice study. From the calves link "It is concluded that faecal shedding of vaccine rotavirus demonstrable by electron microscopic examination is uncommon following oral inoculation of calves with the bovine rotavirus-bovine coronavirus vaccine." From my limited abilities as a layman it is clear that no one rule can be extracted from any of these studiea. It is clear that virus can be but not always is shed after vaccination by a live vaccine. In taking the teacher like stand you take you are only discouraging people from enquiring and ask questions. Once more you have appointed yourselfas the great all knowing oracle. stop trying to bully people. lighten up for your own sake. and for everyone elses. grow up.
