• Vaccination programs for broilers should be developed in
consultation with trained poultry veterinarians and must be based
on local disease challenges and vaccine availability.
• Vaccination will be more effective when disease challenges are
minimized through well-designed and implemented biosecurity and
management programs.
• Vaccination alone cannot protect flocks against overwhelming
disease challenges and poor management practices.
• Every bird must receive the intended dose of vaccine.
• Breeder flock vaccination programs must be accounted for when
designing an appropriate vaccination program for broiler progeny.
