I think you may be living in a square mile surrounded by reality. While it may not get to the exact picture you paint, leverage in the form of strong antics could be expected.  They've already removed kids who refuse vaccine from schools and child protective services have taken kids from parents who refuse to have them vaccinated. What if you faced arrest under expanded "child endangerment" and/or "child abuse" laws, lose your job or SS benefits, get audited or other strong-arm methods governments use to make people more compliant?  Actually, I'd expect an outright law on vaccinations to be required, with strong financial and criminal provisions for non-compliance.  That'd be the ones where 17 emergency vehicles, armored men w/long guns and night vision end up at your front door and on your roof. So, no, I doubt they'd do it on your front lawn.
