Clostridium Chauvoei + Clostridium Novyi + Clostridium Perfringens Type C Bacterin Toxoid + Clostridium Perfringens Type D Bacterin Toxoid + Clostridium Septicum + Clostridium Sordellii + Haemophilus Somnus Bacterin Toxoid Adverse Event Insights

The FDA Center for Veterinary Medicine database currently holds 17 adverse event reports referencing Clostridium Chauvoei + Clostridium Novyi + Clostridium Perfringens Type C Bacterin Toxoid + Clostridium Perfringens Type D Bacterin Toxoid + Clostridium Septicum + Clostridium Sordellii + Haemophilus Somnus Bacterin Toxoid, including 15 reports in which the animal died — a 8820.0% case-fatality figure among reported events only, not a population-level mortality rate. Active ingredients on file: Clostridium Chauvoei, Clostridium Novyi, Clostridium Perfringens Type C Bacterin Toxoid, Clostridium Perfringens Type D Bacterin Toxoid, Clostridium Septicum. Reported administration routes include Subcutaneous, Unknown. These numbers reflect voluntary submissions from pet owners, veterinarians, and manufacturers and therefore under-represent mild events and over-represent severe ones — a pattern the FDA has documented repeatedly for pharmacovigilance datasets.

The species most frequently named in Clostridium Chauvoei + Clostridium Novyi + Clostridium Perfringens Type C Bacterin Toxoid + Clostridium Perfringens Type D Bacterin Toxoid + Clostridium Septicum + Clostridium Sordellii + Haemophilus Somnus Bacterin Toxoid reports are Cattle (17 reports), with Cattle accounting for the largest share. Within those species, Cattle (other) (10), Aberdeen Angus (5), Crossbred Bovine/Cattle (1) appear most often — though breed popularity and ownership density shape these counts as much as any drug-specific sensitivity. This distribution matters because the same active ingredient can behave very differently across body sizes, ages, and species physiology.

The most commonly reported clinical signs associated with Clostridium Chauvoei + Clostridium Novyi + Clostridium Perfringens Type C Bacterin Toxoid + Clostridium Perfringens Type D Bacterin Toxoid + Clostridium Septicum + Clostridium Sordellii + Haemophilus Somnus Bacterin Toxoid are Death (14), Lack of efficacy - NOS (8), Lack of efficacy (bacteria) - NOS (4), Necropsy performed (3). Of the 34 reports with a coded outcome, Died is the leading category at 44.1%. Because FDA adverse event data describes correlation rather than causation, these figures are best used to frame informed questions with a veterinarian and to compare reporting patterns across related products — not as a standalone safety verdict on Clostridium Chauvoei + Clostridium Novyi + Clostridium Perfringens Type C Bacterin Toxoid + Clostridium Perfringens Type D Bacterin Toxoid + Clostridium Septicum + Clostridium Sordellii + Haemophilus Somnus Bacterin Toxoid.
