Merck has received the FDA’s fast-tracked approval of a live, genetically modified Ebola vaccine which, according to its vaccine insert, can cause a novel new form of Ebola-type infection, resulting in immunosuppression and possible shedding of live virus to others.
“ Transmission of vaccine virus is a theoretical possibility. Vaccine virus RNA has been detected in blood, saliva, or urine for up to 14 days after vaccination. The duration of shedding is not known; however, samples taken 28 days after vaccination tested negative. Vaccine virus RNA has been detected in fluid from skin vesicles that appeared after vaccination.”
