evidence: Federal regulations revised in 2017 allow the CDC "to detain, medically examine, and release persons arriving into the United States and traveling between states who are suspected of carrying" certain communicable diseases. (Here’s what a sample quarantine order looks like.) Those powers are carried out with help from other federal agencies, such as Customs and Border Protection and the Coast Guard. [...] Vaccination doesn’t get you out of quarantine. Typically, vaccinations aren’t cures; they’re preventive measures. In any case, it’s moot for coronavirus, because there is no vaccine yet. [...] Most quarantine decisions will be up to states and localities, rather than the CDC. People can’t be quarantined for just having a fever; they have to be shown to have been exposed to a specific set of diseases. Most quarantines are done voluntarily, not by force of the state. And vaccination is not a ticket out of quarantine. We rate the statement False.
