The emerging risks of live virus & virus vectored vaccines: vaccine strain virus infection, shedding & transmission nvic referenced report � nov. 2014, page 2 table of contents can people receiving live virus vaccines transmit vaccine. Mmr is a live vaccine and based on research, the measles and mumps attenuated viruses do not cause shedding. the rubella virus has been found to rarely shed into breast milk. the rubella virus has been found to rarely shed into breast milk.. Although rotavirus vaccines are known to be shed in stools, transmission of vaccine-derived virus to unvaccinated contacts resulting in symptomatic rotavirus gastroenteritis has not been reported to our knowledge..
It would be what one might call vaccine fallout. people who receive live-virus vaccines, such as the mmr, can then shed that live virus, for up to many weeks and can infect others. other live-virus vaccines include the nasal flu vaccine, shingles vaccine, rotavirus vaccine, chicken pox vaccine, and yellow fever vaccine.". The injectable flu vaccine does not shed!, in the sense that the vaccinated person spreads the virus from the vaccine. the live virus vaccine can shed, though this article does not discuss that topic. those vaccinated, when infected with the flu, shed/spread more of the naturally acquired infection. i hope this helps.. Otherwise, persons who receive mmr or its component vaccines do not transmit measles, rubella, or mumps vaccine viruses (206,207). thus, mmr vaccine can be administered safely to susceptible children or other persons with household contacts who are pregnant to help protect these pregnant women from exposure to wild rubella virus..
