tetanus - diphtheria vaccine
How does this medication work? What will it do for me?
This medication belongs to a group of medications known as vaccines. It is used to prevent tetanus and diphtheria. This vaccine is recommended for all individuals 7 years of age and older (including those who have previously had tetanus or diphtheria), as well as for people with HIV.
This vaccine increases a person’s defences against the toxins produced by tetanus and diphtheria bacteria. It works by introducing very small amounts of bacterial and toxin components into the bloodstream. Only certain parts of the bacteria are used to make the vaccine (therefore they are not alive), and the toxins have been detoxified. Still, these components are enough to stimulate the production of a person’s own antibodies (cells designed to attack that particular bacteria or toxin), which will remain in the body ready to attack any future bacteria that may cause infection and deal with the toxins produced during tetanus or diphtheria infection.
