If you are talking about flu shots this is the rule of thumb for many doctors here in Canada. If you have Diabetes, breathing problems such as Asthma, bad Allergies, have a heart condition or any other serious disease, or you are very young or elderly, then you should have the flu shot. If you are healthy then you shouldn't get the flu shot. The reason for this is because your immune system should work at fighting many of these "bugs" so it strengthens itself. Some people don't take well to the flu shot and can actually become very ill getting the very flu that you aren't suppose to take. There is great controversy from doctors, etc., over this fact, but the people who get sick from it tell a different story. Please note, that not all people get ill from their flu shot. While the flu season is here it's best to stay away from crowded areas such as movie theaters, etc., but you can't live in a plastic bubble. Make sure you wash your hands often == == * Yes or no. Depends on the disease. See your doctor.

It's best to use a vaccine when you have a disease or your gender might get the kind of disease.
The purpose of a vaccine is to expose an otherwise naive immune system to the pathogen, so it can recognise and quickly respond to that pathogen if it encounters it again. If you've already had the disease, your body will already recognise it if it sees it again.
vaccine
At least one vaccine that was used that caused these problems was the Swine Flu vaccine given in the US in 1976 for one of the earlier strains of "Swine Flu" in humans. Many people died or contracted Guillian-Barre syndrome from the vaccine, more than were impacted by the disease itself. The method of preparation of vaccines has been changed and improved greatly, so this type of response to the newer vaccines is no longer anticipated.
