I'm not a big fan of WorldNetDaily news- they have a pretty strong anti-government and ultra conservative bias that is not my flavor..JMHO.
Anyway, the article danced all around the real issue about why thimerisol is in the news again and that is because of the Andrew Wakefield study. His study showed a link between vaccinations (primarily MMR and thimerisol) and autism. After everyone got all up in arms about it and started refusing vacs, it was revealed that Wakefield accepted study financing from a group of lawyers who were in line to profit from "vaccinations cause autism" lawsuits. This is a major ethics violation and cast doubt on Wakefield's work- so much doubt that many of Wakefield's co-authors and supporters had their names removed from the study work and other Wakefield associations. Even the Lancet (which published the origional study) responded by stating that had they known more about what Wakefield was up to, they would have never published the study in the first place. He was required to make public his cozy lawyer relationship but neglected to reveal it at publishing time, which he did not do.
Scientists should always reveal ethical issues, and their studies should always be peer reviewed. Many balls were dropped in this case and Wakefield's work has not survived peer review. That's one of the things that makes science so reliable- false results WILL be found out (remember cold fusion?).
Here is a an article from Nature.com regarding the Wakefield problem for those interested: http://www.nature.com/nsu/040223/040223-1.html
The problems with Wakefield were all over the news everywhere a couple of weeks ago.
It's interesting (to me) that after the study was discreditied, many people on the anti-vac and autism websites wouldn't accept the criticism and came up with about 100 reasons about why people were 'out to get' Wakefield- everthing from he just was unpopular, to a giant governmental coverup, to being 'paid-off' by the pharmaceutical companies. Not many were willing to consider that Wakefield had an agenda (additional funding from the lawyers).
I view those sites (and others) because my son is autistic and I like to keep an up to date on autism issues.
Anyway, I'm not advocating we all go get a dose of thimerisol, but the reason the CDC, etc., doesn't recommend against the vac preps is because *reputable* studies show it causes no harm, not because they are trying secretly to hurt people. For poeple not comfortable with the preservative, I agree that having an alternative is a good thing. The alternative is better that not vaccinating in my opinion (and not everyone agrees)- exactly the CDC's stance. This is in line with the 'customer service' attitude so popular in healthcare today.
Current autism theory is looking at genetics (chromosomes 7 and 15 seems to have problems), brain abnormalities (smaller, stunted, abnormal neurons have been seen on autopsy), and environmental factors.
Personally, I feel my son's autism was caused by a genetic predisposition couple with an environmental trigger (extreme prematurity).
