Best Spectrum of Protection

Because viruses do not respond to antibiotics, prevention is essential. Guardian® vaccine offers real-world protection against the viruses that are often the cause of calf scours, including coronavirus and rotavirus.


Bacterial intestinal infections can be the most deadly forms of calf scours. E. coli infections can result in death rates over 50 percent. Guardian vaccine’s unique manufacturing process provides concentrated, focused E. coli immune response.


Guardian also provides the broadest clostridium protection ever brought to market. The toxins from C. perfringens can cause death within 24 hours, in spite of treatment.


GUARDIAN VACCINE’S UNIQUE ANTIGEN SPECTRUM

  • Rotavirus
    • G6: 66 percent of all rotavirus infections are G61
    • G10: 7 percent of all rotavirus infections are G101
  • Coronavirus
    • Type 1: 14 percent of an eight state sample of coronavirus infections were Type 12
    • Type 3: 86 percent of an eight state sample of coronavirus infections were Type 32
  • Perfringens
    • Type B, C and D: Only GUARDIAN protects against all three types.
  • K99 E. coli
    • GUARDIAN is the only scours vaccine manufactured with K99 E. coli subunit technology, which produces clean pilus antigens.
    • K99 antigen is the protective part of the E. coli, essential for vaccine efficacy.
    • Whole E. coli vaccines contain cell wall endotoxins that increase the risk of systemic reactions such as abortion, anaphylaxis and even death.

No other scours vaccine is this comprehensive in its coverage.
