What are the complications of immunization against tetanus?
There are very few. The vaccine contains neither living nor dead bacteria – it is made from a fragment of the tetanus toxin and the vaccine is called tetanus toxoid. Transient soreness and stiffness at the site of injection (usually the upper arm) can last several days. Sometimes a nodule forms especially if the injection was not given deeply enough. However, many people have no reaction at all.
