Norvax® Strep Si is an inactivated vaccine against streptococcal disease for immersion or injection vaccination in susceptible fish species like Asian seabass (Barramundi; Lates calcarifer).

Norvax® Strep Si has the following features:
  • The first monovalent immersion and injection vaccine against Streptococcus iniae
  • Proven high and long-lasting protection
  • Safe for the fish, the vaccinator and the consumer
  • An important Norvax® vaccine, targeted at an important warmwater disease
  • Benefits sustainable and environmentally friendly aquaculture
Norvax® Strep Si is a monovalent vaccine containing an inactivated strain of Streptococcus iniae. The vaccine induces protective immunity in warmwater fish of both marine and freshwater environments against streptococcosis caused by Streptococcus iniae. Streptococcosis will affect the fish in the grow-out facilities. Therefore, fish should be vaccinated before they are put into cages, pens or ponds. If fish have to be transferred before reaching injection size (> 20 g), immersion vaccination should be done on smaller fish (> 3 g) one to two weeks before transfer. Then, when reaching injection size, fish should receive a booster vaccination by means of a single intraperitoneal injection that will protect them up to market size.

Norvax® Strep Si - Product Data Sheet

Product class Vaccines
Target species Fish species susceptible to Streptococcus iniae infections
Description Inactivated vaccine against streptococcal disease for immersion or injection vaccination in susceptible fish species like Asian seabass (Barramundi; Lates calcarifer).
Composition Inactivated strain of Streptococcus iniae.
Formulation Water-based suspension for immersion or injection.
Indications For active immunization of susceptible fish species to aid in the protection against streptococcal disease caused by Streptococcus iniae.
Dosage The preferred method for vaccination is by intraperitoneal injection from 20 grams and onwards. If early protection is needed, fish can be vaccinated by dip immersion from 3 grams and onwards. However, this alone is not sufficient to achieve a long duration of protection. Therefore, the fish should be re-vaccinated by intraperitoneal injection as soon as the size of the fish allows for this. Immersion: One litre of vaccine is mixed with 9 litres of seawater. Using a knot less hand net, immerse 3 kg of fish into this vaccine solution for 30 seconds. Prepare a new vaccine solution after having vaccinated 100 kg of fish. Ensure good oxygenation or aeration during immersion vaccination. Maintain pH and temperature stable throughout. Injection: Inject 0.1 ml vaccine intraperitoneally at the ventral side of the fish, just behind the pectoral fin-tip.
Withholding period Nil. (National regulations should be observed).
Presentation Norvax® Strep Si is available in 250-ml PET bottles.
Storage Store and transport between 2 and 8°C. Do not freeze. Once opened, bottles should be used the same day. Don't use after the expiry date.
Contra-indications None
Further information Vaccination is recommended for fish at or above 35 grams. The water temperature at vaccination should be at or below 15°C. Fish should be withheld from feed for 1-2 days before vaccination. Fish should be anaesthetised according to veterinary recommendations. Start feeding, at the earliest, 12 hours after vaccination. Only healthy fish should be vaccinated. Do not use in breeding stock. No information is available on the safety and efficacy from the concurrent use of this vaccine with any other. It is therefore recommended that no other vaccines should be administered within 14 days before or after vaccination with this product. Shake well before use. Sterile injection equipment should be used. At least 500 degree days are recommended from vaccination to potential exposure to furunculosis, vibriosis, coldwater vibriosis, wound disease or IPN.
Undesirable effects When undesirable effects occur, they are normally seen in the abdominal cavity. Vaccinated animals normally show very slight to moderate adhesions between viscera or between viscera and the abdominal wall. The eventual adhesions may be removed manually and are thus not severe. Occasionally, vaccinated populations may show adhesions between greater parts of the abdominal organs, granulomas and/or more massive pigmentation. Such lesions are typically seen in < 10% of the treated animals.
Precautions/Warning To the user:
This product contains mineral oil. Accidental injection/self injection may result in severe pain and swelling, particularly if injected into a joint or finger, and in rare cases could result in the loss of the affected finger if prompt medical attention is not given. If you are accidentally injected with this product, seek prompt medical advice even if only a very small amount is injected and take the package insert with you. If pain persists for more than 12 hours after medical examination, seek medical advice again.
To the physician:
This product contains mineral oil. Even if small amounts have been injected, accidental injection with this product can cause intense swelling, which may, for example, result in ischemic necrosis and even the loss of a digit. Expert, PROMPT, surgical attention is required and may necessitate early incision and irrigation of the injected area, especially where there is involvement of finger pulp or tendon.


GENERAL REMINDER:
Usage instructions & withdrawal periods may vary by Country.
