I would be happy to meet with Lady Matilda and set up vaccines for both her and her daughter, as well as give her information about germs and any other health matter she wishes.
You can come in for vaccines only, if that is your choice. Informed consent is an important part of health care.
That said, I must stress the importance of a physical. Simple non-invasive checks of blood pressure, vision, hearing, dental exams, skin checks, can prevent so many health problems. Listening to the heart and lungs with a stethoscope can detect problems before they become life threatening. Blood tests are important so that I know your blood type in case of emergency. Also, a small amount of blood allows for screenings for anemia, cholesterol levels, diseases and more. Simply looking at the back and posture can let me know if there is an issue with the spine.
There is more than germs to learn about. For example, are you aware of the importance of sunscreen when travelling through doors?
