After you gave a cow with blackleg a shot you accidentally stuck yourself with the needle can you get the disease?

You haven't been exposed to blackleg (a Clostridial bacterial infection) as the vaccine is a killed vaccine, but it would be a good idea to keep a close watch on how you feel for the next week and watch the accidental injection site as well. If you start to run a fever or notice swelling, redness or pain around the injection site, see a human doctor immediately and let them know this was an accidental needle stick from a cattle vaccine.
