Experts confirm aluminum in Hep B vaccines is safe and not linked to allergies, despite renewed claims by RFK Jr. in a circulating video.
A Danish study shows aluminum in vaccines is safe. We break down the real data and debunk the myths spread by anti-vaccine activists.
No, mercury in vaccines isn’t dangerous. Thimerosal is safe, doesn’t build up, and isn’t linked to autism. The vaccine schedule saves lives and money.
Thimerosal in flu shots isn’t dangerous—learn how it’s different from toxic mercury, what studies show, and why vaccines are not linked to autism or brain harm.
Do vaccines contain RoundUp? A viral video says yes—but flawed testing and basic science say no. There’s no credible evidence glyphosate is in childhood vaccines.
Do MMR vaccines contain aborted fetal cells? RFK Jr. says yes—but the truth is vaccines are made using decades-old cell lines, not fetal “debris.” Even though fetal cells are used to grow vaccine viruses, vaccines do not contain these cells.
Do vaccines contain aborted fetuses? No—some use decades-old fetal cell lines for development, but no new cells are used. Learn the facts behind this persistent myth.
Do flu shots weaken your immune system? Anti-vaccine claims distort studies, but real data show flu vaccines protect against illness, not increase infection risk.
Explore the truth behind aluminum in vaccines. This post debunks claims of inadequate testing with evidence from extensive clinical trials and decades of safety data.
