Layer Vaccination with our Less is More approach

1. What is the Less is More layer vaccination strategy?

The Less is More layer vaccination strategy is an approach that aims to reduce the number of vaccine applications while maintaining effective protection against major poultry diseases thanks to innovative new technology vaccines.

It typically relies on:

• Early vaccination at the hatchery
• Compatible new technology vaccine combinations
• Long-lasting immunity

The objective is to optimize protection while improving operational efficiency and bird welfare.

2. How can vaccination programs be simplified without reducing protection?

Vaccination programs can be simplified by optimizing how and when vaccines are administered, rather than reducing disease coverage.

This can include:

• Moving key vaccinations to day-old (hatchery level)
• Combining compatible vaccines into fewer administrations
• Using technologies that provide sustained immunity over time

When properly designed, simplified programs can maintain or even enhance protection while reducing complexity.

3. What are the benefits of reducing the number of vaccine applications in layers?

Reducing the number of vaccine applications can provide multiple benefits:

• Operational efficiency: less labor and easier scheduling
• Animal welfare: reduced stress from handling
• Consistency: more uniform vaccine delivery across flocks
• Performance: improved productivity due to lower stress and better health

Overall, fewer interventions can lead to more stable flock performance.

4. Why is hatchery vaccination important in simplified programs?

Hatchery vaccination plays a key role in the Less is More, simplified strategies because it allows early, uniform, and controlled vaccine administration.

Key advantages include:

• Consistent delivery to all chicks
• Reduced need for field interventions
• Better integration of combination approaches

It is increasingly used as the foundation of modern layer vaccination programs.

5. How do I design the right vaccination program for my layer operation?

An optimal vaccination program should be tailored to your specific production context.

Key factors to consider include:

• Local disease pressure
• Production system (multi-age, free-range, etc.)
• Biosecurity level
• Economic and operational constraints

A simplified vaccination strategy does not mean a standard approach—it means designing a program that achieves effective protection with the least possible complexity.
