We already have our entire kingdom protected, but we need to talk about our medical facilities.
What do you mean? We have the best medicine in all the kingdom!
We do not! Nearly half of our subjects have fallen ill to this corona virus! We need to improve our medicinal practices immediately!
What do you care if some peasants have fallen ill? We do not have the time nor resources to focus on such privileges!
I have already experienced the pain of this virus! (Specific) I am almost immune! It is difficult to prevent because its spread through the air! If only people would distance from each other. At least then, there would be less fevers! (nonspecific)
A sickness that travels through the air? I have never heard of such blasphemy!   -cough-
Are you feeling alright? Have you taken a vaccine or antibiotics? Those help the T-cells fight the viral pathogens and teach the antibodies to fight them.
Yes, yes. I am fine. -Cough-
Have you considered getting the vaccine? It injects a weakened or dead version of the virus into your blood stream so your body can learn to fight the real thing. 
Hello, I head you had some symptoms of COVID-19. Is this true?
I have not. I think the best cure is the disease.
Yes, I have had a fever as well.
I highly suggest taking the vaccine your highness. It can only help you, and let your B-cells produce more antibodies to fight the vaccine. 
You know what? I think I will. When can I get one?
