Robert F. Kennedy Jr., the US health secretary, has called for removing thimerosal from all flu vaccines. But what does research say about its safety?
Thimerosal, an ingredient used in multi-dose vaccine vials, is under scrutiny due to concerns over its potential harm. However, numerous studies suggest that it may not pose a significant risk to public health.
In June, a vaccine advisory panel recommended removing thimerosal from flu vaccines. But what do the experts say? Research indicates that thimerosal has been extensively tested and found to be safe. Studies have consistently shown that the benefits of using thimerosal in vaccines far outweigh any potential risks.
The FDA and CDC have also approved thimerosal for use in vaccines, citing its safety record. In fact, a study published in the Journal of Infectious Diseases found that thimerosal did not increase the risk of autism or other adverse effects.
It’s essential to separate fact from fiction when it comes to vaccine ingredients. While RFK Jr.’s advocacy is well-intentioned, more research and evidence are needed before making any decisions about removing thimerosal from vaccines.
