That's not really what I meant. I was talking about people at risk. The translation may not have reflected my thoughts well.
When we talk about people at high risk, we're talking about people for whom this drug could be prescribed, in addition to all the other measures. Often, these people aren't covered by any drug insurance. It is very difficult to get people to take medication preventively, especially when they don't have insurance coverage, since taking these medications makes no difference in their daily lives.
Could having universal drug coverage help to conduct research and then apply the results? Wouldn't that make it more likely that people will take the prescribed medications, especially if they are at high risk and don't have any insurance coverage?
