To speak of a concrete example: in Poland I found myself in a company of doctors who were complaining about the anti-vaxx movement. I asked them when there was the last public campaign on vaccinations - you know, like we saw in 50's with posters, TV programs, articles etc.
The answer was silence.
And there's a dozen of institutions that have funds just for that: ministry of health, public insurer, all kind of medical associations etc.
