Early intervention: This allows for preemptive immunization, addressing the issue of early infections in livestock production where traditional single-virus strains have not yet been vaccinated.

Advantages: Gene-engineered vaccine with advanced production technology and excellent immunogenic efficacy.

IV. Product Usage

[Effects and Uses]:

For the prevention of infectious laryngotracheitis and fowlpox in chickens. The immunization period lasts 5 months.

[Dosage and Administration]: Refer to the product instructions for details.

According to the feather count specified on the bottle label, dilute the solution with normal saline and administer subcutaneously at non-vascular sites on the inner wing surface of chicks aged ≥21 days. Within 3–4 days post-inoculation, mild redness and swelling may occur at the injection site, occasionally accompanied by crusting; symptoms typically resolve by day 14.

[Adverse effect]:

Generally, no visible adverse reactions are observed.

[Matters need attention]:

(1) This product is intended solely for vaccination of healthy chickens. It must not be used in chickens with weak constitutions or those previously exposed to fowlpox virus, as this may compromise immunization efficacy.

(2) Carefully inspect the product before use. If any of the following conditions are observed—cracked vaccine vial, absence of label, or presence of impurities in the vaccine—do not use it.

(3) The diluted vaccine should be stored in a cool, dark place and used within 4 hours.

(4) Used vaccine vials, injection devices, and similar items shall be subjected to sterilization.
