If your grandparent got vaccination for a disease why didnt their offspring get vaccination for that disease?
There are many ways that differ from disease to disease for these diseases. Quarantine is often effective for many of these. Typhoid can often be prevented by improving sanitation of food and water supplies. However the way that is universally effective for all of these is vaccination. Of course a different vaccine must be prepared and administered for each.
Animals are susceptible to a wide variety of diseases that are treatable. Some of the more common are: - bacterial infections, which can usually be treated with antibiotics - metabolic conditions like diabetes, which can usually be treated/managed with hormones and supplements - cancers, which can sometimes be treated with surgery and chemotherapy Most viral infections are not treatable, but some can be prevented through vaccination.
The vaccination process is intended to boost the immune system against infectious diseases and similar problems by introducing a small quantity of the disease to the immune system, so it knows what to look for and how to fight it. However, vaccination does not make you immune, so always exercise as much caution as possible in a situation in which you might be at risk of contracting an infectious disease.
