I cut my finger against a metallic screen. i got a tetanus shot but had to wait 2 1/2 days because it happened over the weekend. odds of tetanus?

Low: If you completed the primary tetanus shot series at any point in your life, the booster just revives the response.People do have a few days, but the sooner the better or some forget. Your risks increase when the wound is left dirty or is contaminated with landscaping soil. I assume you cleaned the wound which helps most avoid the infection that sets the stage for tetanus.
