This does happen here. But it's tucked away in the dark and never discussed. The sad part is that ALL vaccines given to us have been found to be contaminated with foreign objects, even tiny shards of GLASS!! The cleanest vaccines without cross-contamination or foreign objects? The ones we give our pets. . . . Our dogs have a higher health standard than our children!
