You can consult a general physician or an infectious disease doctor.
2. If I just received the yellow fever vaccine, should I avoid contact with my immunocompromised family member?
It is not necessary to isolate yourself from people with weak immune systems as there is no evidence that people who receive yellow fever vaccine shed the vaccine virus.
3. How long does yellow fever vaccination last?
A single dose of yellow fever vaccine provides long-lasting protection. Some people may benefit from a booster dose of the vaccine either because they have problems with their immune system or they are in endemic areas.
