What are the risks of being vaccinated against certain diseases?

You have a risk if you have a severe allergic to vaccine or its components.

Explanation:

A contraindication is a situation in which a medication, in this case a vaccine, should not be administered, under any circumstances, because of the high risk that a serious or even fatal adverse reaction may occur. In the case of a precaution the risk of an adverse reaction is lower and the administration can be considered based on the possible benefit, weighing the foreseeable advantages and disadvantages.

Contraindications can be permanent or temporary. Most contraindications are temporary. There are very few permanent contraindications to vaccines.

The only contraindication applicable to all vaccines is the existence of a severe allergic reaction prior to said vaccine or one of its components.
