Billions of dollars aren't spent to modify a vaccine just to mollify a small community of questioners, who weren't even that great in number at the time of conversion. If anything, it would benefit the vaccine makers - fewer side effects to impede sales, and more sales because more boosters are needed (though I doubt there's anything that nefarious at play in this specific case).
Here's a post-marketing study about the increased safety profile of the acellular vaccines vs. the cellular vaccines: http://www.ncbi.nlm.nih.gov/pubmed/8620224 http://www.ncbi.nlm.nih.gov/pubmed/8620224
- tokenadult 13y agoThanks for the link, but that study was very soon after the change and ignores the issue of whether vaccine effectiveness was the same (as history appears to be showing it was not). And that is the point. A small reduction of minor reported adverse effects for a large reduction of immunization effectiveness is usually not counted as a good trade-off by epidemiologists.
