The smallpox vaccine comes from cows. Most diseases you a weakened form of the disease. However the smallpox vaccine is brought from cowpox. (closely related to smallpox but not as dangerous). You cannot get this vaccine anymore and if you did it would result in a bad reaction.
Simply put there are to many diseases. Some of the existing vaccines, pneumovax for example,only protect against a certain bacteria, and the flu vaccine is redeveloped each year to protect against the strain that is predicted to be the most prevalent. Others, like shingles vaccine protect against the disease, do NOT guarantee immunity but help to lessen the severity and pain associated with the disease.
Diarrhea is a symptom of several diseases, not a disease itself. Therefor there is no vaccine for diarrhea. But there are vaccines for some of the diseases that cause diarrhea as a symptom. However there are also non-disease causes of diarrhea and for these there will never be a vaccine, as there is nothing to vaccinate against.Diarrhea is also a symptom of several types of poisons as well as radiation sickness and although these can be considered "diseases" or "illnesses", there is no disease causing organism to vaccinate against so there will never be a vaccine.

They can almost any diseases any horse would get. But some of them are more prone to lung diseases from racing.

It's a vaccine for a bacteria, Haemophilus influenzae type B. Thanks to the effective of the vaccines, most doctor these days have no idea what it was like before when it caused childhood menigintis, epiglottitis, pneumonia, ect. This is actually true with quite a few diseases like polio, smallpox, even chicken pox. It's so rare to see these because the vaccines were so effective that the parents are more concern about the side effects of the vaccines than the disease themselves. No one remembers what it was like before the vaccines!
Events that led to Edward Jenner's discovery of the smallpox vaccine.(APEX)
Live bacteria
They can but it most likely doesn't happen. Like a 1 in 1 billion chance!
Those who are vaccinated will not unknowingly pass vaccine-preventable diseases onto those who cannot fight the disease, such as the elderly, the young, and those with compromised immune systems.
