Yellow fever vaccination - Who should not be vaccinated?

People who should not have the yellow fever vaccination include:

Babies under nine months of age: Babies who are six to nine months old should only be vaccinated if the risk of getting yellow fever during travel is unavoidable.
Pregnant women: unless the risk of yellow fever is unavoidable.
Breastfeeding women: unless the risk of yellow fever is unavoidable.
People whose immune systems are lowered (immunosuppressed): Such as people with HIV and those receiving chemotherapy or radiotherapy.
People who are allergic to eggs: The vaccine contains small amounts of egg.
People who have had a severe allergic reaction(anaphylaxis) to a previous dose of the yellow fever vaccine.
People who are allergic to any of the ingredients in the vaccine.
People who have a condition that affects the thymus gland (part of your immune system that is located in your upper chest).
People who are currently very unwell (for example with a high fever): This is to avoid confusing the diagnosis of your current illness with any side effects from the vaccine.
Elderly yellow fever naïve travelers: Those who have not been previously exposed to the vaccine who are 60 years of age or over (unless the risk of yellow fever is unavoidable).
