The way you write about Andrew Wakefield is dodgy. you repeat the allegations without discussing any evidence against them. You say the 10 authors retracted. what they said was no causal link was established in the paper between MMR and autism. In fact the paper never made that claim. So. Here was everything in the original paper about vaccines: two sentences in the conclusion: 'In most cases onset of symptoms was after measles mumps and rubella immunisation. Further investigations are needed to examine thsi syndrome and its possible relation to this vaccine. ' So the retraction was retracting nothing. You don't mention that the other co-author, Professor John walker-Smith was completely exonerated on appeal. None of this subtlety makes it into your piece, which is a pity.
