Chicken pox might seem like a mild infection to some, but it can have very serious complications and children can die, and have died, from CP. There was a boy who died from CP complications in my home town, it was horrible.
My son has an underlying autoimmune disease, and if he contracts any of these illnesses, he is at a very high risk of serious hospitalisation (and worse ). He has had the vaccinations, but they are obviously not 100% effective and he can still contract it. PLEASE, I implore you to think of children like this when you are tossing up whether or not to vaccinate. Especially if you are already a vaxxer.
This is straight from the QLD fact sheet:
Measles should not be regarded as a simple mild disease. Deaths occur mainly in children under five years of age, primarily from pneumonia, and occasionally from encephalitis. Complications are more common and more severe in people with a chronic illness and very young children.
