> That's a good point. You can agree that its within the federal authority to mandate vaccines, but it really should be a decision made and explicitly endorsed by elected representatives rather than some agency (Centers for Medicare & Medicaid Services) that I have never heard of until now and whose head is appointed by one person.

Jacobson v. Massachusetts[1] established that it is within the State's power to mandate vaccinations, so shouldn't this be up to individual states? I'm also pro- nationwide mandatory vaccinations, but Congress also doesn't seem to be the right way to do it.
