Streptococcus Equi Bacterial Extract

For use in healthy horses of all ages as an aid in the reduction of disease (strangles) due to Streptococcus equi infection.

  • Promotes phagocyte destruction of virulent S equi
  • Reduced risk of sensitization; well tolerated by most horses
  • Contains a purified M-protein antigen extracted through an exclusive process
  • Sensitizing elements of whole cell bacterins are virtually excluded in the extraction process
  • Available in 1 mL dose and 10 mL dose

Field reports suggest certain hypersensitive horses may demonstrate local or generalized reaction, sometimes severe, following exposure to streptococcal proteins. Studies indicate exercise following vaccination decreased incidence and duration of reactions.

  • The only S. equi vaccine that can be administered IM.
  • A purified M-protein antigen extracted through an exculsive process which promotes destruction of virulent S. equi.
  • Exclusion of sensitizing irritants of whole cell vaccines of the past, reducing the risk of vaccine reactions.
  • Does not require reconstitution or intranasal injection, making Strepvax an attractive option for practitioners who desire convenience and ease-of-administration.
  • Killed vaccine with no risk of reversion to virulence.

Using aseptic technique inject 1 mL IM preferably in the hind quarters. For primary vaccination give 3 doses at intervals of 3 weeks. Foals vaccinated when less than 3 months of age should receive an additional dose at 6 months. Revaccinate annually and prior to anticipated exposure.
