Innovax-ILT-SB is an innovative vaccine that protects against both infectious laryngotracheitis (ILT) and very virulent Marek’s disease (MD). It is a highly effective method of ILT control and provides safe, long-term protection.

How It Works

When Innovax-ILT-SB is applied, it causes an immune response in the vaccinated chicken. The production of antibodies against the I and D glycoproteins stops the actual ILT virus from attaching itself to the cells to prevent infection. Innovax-ILT-SB also results in an immune response against very virulent Marek’s Disease (MD) because it includes the SB-1 strain of chicken herpes virus (serotype 2). It causes the activation of natural killer cells and macrophages, as well as the production of antibodies. Learn more by watching our Mode of Action Video.

Long-Lasting, Reaction-Free Protection

No vaccine reaction

Innovax-ILT-SB uses the herpesvirus of turkey (HVT) as its foundation to deliver long-lasting protection against both ILT and very virulent Marek’s Disease without the costly reactions of conventional live vaccines. Convenient to use, Innovax-ILT-SB can be administered by in ovo injection of 18-day-old chicken embryos and can be easily combined with other respiratory vaccine programs. It supplies long-term immunity and there are no post-vaccine reactions.

Healthier Flocks, Increased Productivity

improved bird performance

The innovative Innovax-ILT-SB vaccine has many advantages over traditional live virus vaccines to improve overall flock health and performance. By eliminating the risk of ‘rolling reactions’ flock health is enhanced, and without the need for revaccinations in the field labor costs are also lower. Using an HVT-based vaccine delivers more effective disease control too – live ILT virus cannot be spread in the poultry house and the risk of interference between live vaccines against other respiratory diseases is removed.


easy to administer

Effective protection begins at the hatchery with in ovo application. As a replacement for Marek’s only vaccination, Innovax-ILT-SB does not change any hatchery vaccination processes.

Convenient to use, Innovax-ILT-SB can be administered in a single dose in the hatchery by the in ovo route and can be easily combined with other respiratory vaccine programs.
