how often should you have tetanus shot
How often should you have a tetanus jab and is there a limit to how many you can have? As a general rule you should have a tetanus booster every 10 years because immunity is provided for this length of time from each immunisation. If it has been longer than this since a previous injection, a course of injections will boost your immunity back to fully protected levels and enable the 10-yearly cover to restart.
