Some health policy experts say Kennedy's early moves as HHS Secretary are concerning and suggest that he could undermine immunizations in less direct ways.
He probably believes that vaccines are bad and people should eat healthier.
So he's been given control of health care to dismantle it rather than be given control of the department of agriculture where he would push for better food practices.
In terms of politics, "the freedom to choose" not to vaccinate.
The "saner" arguments of the anti-vax movement is parents and individuals should have the right to not vaccinate.
But bare in mind that these arguments are rooted in the same conservative arguments: rules apply to YOU. They don't apply to ME. I am a Christian and therefore know what's best. The law exists to protect me from YOU and allow ME to punish YOU.
Bottom line is that this isn't about vaccinations as much as it is about allowing conservatives to ignore government regulations that have been oPpReSsInG tHeM.
You guys know that RFK jr. wrote an article in Rolling Stone that basically introduced America to Andrew Wakefield, the doctor who did the "study" that linked vaccines to autism? While it's true that anti-vaxers have been a thing almost since the founding of the Republic, it was niche until RFK, Wakefield, and finally Jenny McCarthy and Jim Carry (with the help of Socials) took it mainstream and fomented the movement we see today.
