In Sweden you don't really have a plan. Everyone is covered regardless including basic sick pay. You can have zero income, pay zero taxes and file zero forms and still be covered like everyone else. The maximum co-pay per year including everything (treatment, hospital, rehab, equipment, medication etc.) is $300 per year. Some other European systems are more like "US light" where you have to qualify and choose. Some employers in Sweden will cover private treatment, vaccinations and more extensive sick pay (you already get 80% of x1.5 of median income if you are employed). But it isn't really required.
