clostridioides difficile / clostridium perfringens vaccine, inactivated

This medicine is authorised for use in the European Union.


Suiseng Diff/A is a veterinary vaccine given to sows (female pigs that have already given birth to piglets) or gilts (female pigs that have not yet given birth to piglets) to protect their offspring from intestinal disease caused by toxins produced by the bacteria Clostridioides difficile (toxins A and B) and Clostridium perfringens type A (alpha toxin). Suiseng Diff/A contains versions of the toxins that have been inactivated so they cannot cause disease, called toxoid A, toxoid B and alpha toxoid.
