Back in 2008 when the ACLU actually stood up for personal freedom:

"No one should be forced to be vaccinated against their will both because of the constitutional right to refuse treatment, and pragmatically because forced vaccination will deter at least some people from seeking medical help when they need it.” "Following this flawed logic, several state-based proposals have sought to address any ‘public health emergency,’ … [by] resort[ing] to punitive, police-state tactics, such as forced examinations, vaccination and treatment, and criminal sanctions for those individuals who did not follow the rules.”

--The American Civil Liberties Union in 2008
