The main reason for this association is the increasing prevalence of autism and the increase of vaccination coverage. With close proximity to the vaccine it may be coincidental with the apparent onset of autism. In 1998 there was a study published in The Lancet that suggested this connection, it was later found baseless, nonetheless, it was not until 2000 the vaccine manufactures removed thimerosal ( a mercury-based preservative) from all routinely children vaccines due to the high number of public fear. Even though, again the vaccine was not proven to cause autism(3). Cases of autism after the one year mark (regressive autism) may have an onset, however, with the single epidemiological study no association with MMR vaccination was found. Currently, there is no evident that supports a causal association between the MMR vaccine, or any other vaccines and
