People with Down syndrome have a weakened immune system (immunodeficiency). They are more likely to get respiratory tract infections and for these infections to affect the lower respiratory tract and cause pneumonia, bronchiolitis or croup. Infections may be more severe, and it can take longer to recover. Skin conditions, such as eczema, are more common in people with Down syndrome and can be aggravated by chickenpox disease.
Please refer to the special groups factsheet for a list of funded vaccines for people with Down syndrome.
