VACCINE AFFECT

The 2004 Andrews study — funded by the UK Department of Health — analyzed over 100,000 children and reported no link between infant thimerosal exposure and autism, with one possible signal for tics. But because it relied on routine GP records, critics argue the data may have missed diagnoses, introduced bias, and reflected its government funding. The reel covers what the study found — and the next carousel breaks down exactly what critics say.

Critics argue that the study was not sensitive enough to rule out a modest effect.

The 2002 Danish cohort study by Madsen and colleagues is often cited as a cornerstone in the argument against any link between MMR vaccination and autism. However, one of the most important criticisms centres on the fact that the study used diagnosis dates rather than the onset of symptoms.
