What are the conditions, please list all of them in a way that makes it easy for me to find? What age groups does this affect? I think I have condition Y so I should go get vaccinated, but I have conflicting information on that from multiple doctors. Should I get vaccinated? Also, in the US people often take advertised medications to their doctors and ask if they should take it, rather than doctors recommending things to people. Finally, there are large segments of the population that don't consult doctors for varying reasons. You wanna try and make that message simpler?
