Rarely, however, a live attenuated virus, especially in an immunocompromised host, will give the disease, usually a milder form.
Polio is a live attenuated vaccine, about 1 in a million will develop some form of polio from the vaccine. Someone on this or a related thread posted that their relative did get polio from the vaccine, sad, but also VERY rare.
Measles, Yellow fever, Varicella-Zoster and the nasal spray form of the flu shot are all live attenuated viruses in use today. Smallpox was, but since the disease is extinct, that vaccine is no longer given

Good post. Thanks for the knowledge!
