Just because something relies on public funding doesn't make it political.
Public health is one of those. The overwhelming goal is to reduce health problems from becoming so large that infrastructure fails to handle it, as well as prevent death and suffering as a result.
If quarantine is the way to do it, then it makes sense to enforce it. If vaccination is required, then so be it, and the taxpayers foot the bill.
It has nothing to do with political ideology, left, or right, green or brown.
