From Smallpox vaccine uses fetal cell line
"The MRC-5 line was developed … from lung tissue taken from a 14-week fetus aborted for psychiatric reasons from a 27-year-old physically healthy woman," said a description of the cell tissue by the Coriell Institute for Medical Research at the University of Medicine and Dentistry of New Jersey, where the line is maintained. The institute further describes it as "normal human fetal lung fibroblast." Meanwhile, health officials with the Food and Drug Administration say the method of manufacturing the old vaccine, called Dryvax, which was made by Wyeth using calf skin, is "no longer considered optimal." Instead, the agency says the new smallpox vaccine "will be prepared in MRC-5 cells" – a line of aborted fetal cells dating back to 1966 – because that method is more efficient.
For those who do not live by Christian moral standards, I might suggest an Aids test before you go get your smallpox vaccination.
Cancer patients and people that have and/or have EVER had eczema are ALSO at high risk of an adverse reaction to the "vaccine". The vaccine, by the way, has NEVER been shown to be effective against smallpox, and HAS been shown to make those vaccinated MORE susceptable to the disease...
I wonder why can't these vaccines still be used? It seems they were safe. Of course, AIDS wasn't much of a problem back then...
