Without the postpartum and early childcare of those countries.
Denmark doesn't do mandatory vaccines to the same degree as they catch early development of disease and treat it when it appears, consistently across the whole population.
The US has a case for mandatory multi childhood vacination as the data shows otherwise preventable childhood diseases will spread untreated and unchecked.
If you like Japan and Denmark and want the same - get onto improving the US health system for everybody regardless of employment status.
A lot going on in your statement.
Postpartum, childcare is good but I doubt correlated much with vaccine need.
Denmark doesn’t do anything to “catch” disease early in regards to vaccines at least.
There’s data thing is too broad to even discuss really, there’s a whole ton of data and on the specific ones taken off recommendation the data I’ve seen looks not too controversial.
And US healthcare isn’t so bad as people want to make it out to be, we have easy access to vaccines, top tier hospitals, medicine, and low wait times. It’s expensive and overpriced, and unevenly distributed, but also better in many ways than anywhere else.
