US Ends Use of Vaccine Ingredient Targeted by Anti-Vaccine Movements
The US has decided to end the use of thimerosal, a preservative once targeted by anti-vaccine groups, after scientific reviews confirmed its safety, aiming to improve vaccine confidence.
The United States health authorities have announced the discontinuation of a vaccine ingredient that has long been the focus of anti-vaccine conspiracy theories. This decision comes after substantial scientific studies and expert reviews confirmed the safety of the ingredient, which was falsely believed by some groups to cause autism and other health problems.
The ingredient in question is thimerosal, a preservative used to prevent bacterial and fungal contamination in multidose vaccine vials. Extensive research, including assessments by the World Health Organization, has shown that thimerosal does not pose any health risk. Despite this, it has been a target of misinformation, prompting the CDC and other health organizations to reassess its use.
Following a recent panel review convened by vaccine advocate Robert F. Kennedy Jr., experts recommended phasing out thimerosal in influenza vaccines used for children, pregnant women, and adults. Earlier, the FDA had already limited the use of thimerosal in many vaccines available in the US. However, the new policy is seen as a step to address public concerns and combat vaccine hesitancy fueled by misinformation.
The move reflects broader efforts to bolster vaccine confidence and ensure public health safety. Health officials emphasize that vaccines are rigorously tested for safety and efficacy, and the removal of a preservative that is widely regarded as safe is unlikely to impact vaccine protection. Experts warn that continued misinformation can harm vaccination efforts, but committing to transparent and evidence-based policies remains key.
