“It’s “all true” that the measles vaccine wanes quickly, was never fully safety tested and contains fetal debris.”
What PolitiFact found
Scientists say the measles vaccine offers lifelong protection that is 97% effective at preventing the virus. Scientists tested the MMR vaccine before it was approved for use and perform ongoing safety surveillance research; studies show that serious adverse effects are rare. Finally, the MMR vaccine may contain trace amounts of fragmented DNA, but it does not contain whole fetal cells or fetal DNA.
