Question: 

Will it be an issue to revaccinate against tetanus if you are unsure if your child has already had shot

Answer: 

Getting an extra dose of a vaccine when a person’s immunization history is unknown is not harmful and ensures protection. 

Booster doses of tetanus-containing vaccines given too frequently may cause an increased local reaction. We recommend that you discuss this further with your immunizing health care provider.
