Can tetanus occur after 17 months from non bleeding exposure? though teatnus vaccine was taken after 3 months from exposure .

Unlikely: It seems to be unlikely. Follow up with your doctor if you have any symptoms.

This question makes : This question makes no sense. Are you sure you are referring to tetanus? NO!!! Tetanus cannot occur after 17 months, or even after 1 month. We like to immunize everyone to tetanus routinely every 10 years. If there is a serious risk of tetanus and reason to fear a lack of immunity we use tetanus antitoxin as soon as possible.
