More broilers per farm / Higher density/m2
With more broilers per farm, improvement of the biosecurity
procedures is essential.

More broilers per farm / Higher density/m2
These conditions make vaccination in the farms more
difficult to be performed in a proper way.
The worldwide trend is to concentrate vaccination in
the hatcheries.
Hatchery Vaccination – In-ovo & SQ (2012)
Country practicing hatchery Injection (> 10 % of production)
Country NOT practicing hatchery injection (< 10 % of production)
Risk of outbreaks with massive losses
Use of more effective vaccines that are able to reduce
the shedding of challenge pathogens.

Labor scarcity
Vaccination performed in the hatcheries and in a more
automated way through in-ovo or subcutaneous routes.
Reduction of antibiotics
Vaccines that induce strong post-
vaccination reactions (PVR) have been
increasingly replaced by safer vaccines

Conclusions
The industry has completely changed over the past decades
and it has brought new challenges to producers:
Huge production complexes located in very densely populated areas;
High stocking densities in the farms;
High disease pressure;
Poorly qualified workers,
Pressure to reduce use of antibiotics
Pressure for animal welfare
Etc
Within this new context, vaccination procedures have clearly
evolved.
Conclusions
What should we expect from a vaccine?
Safety (in ovo or day-old application to susceptible birds)
Clinical Protection
Increased resistance to infection
Reduction of shedding
Induction of immunity in face of MDA
Long duration of immunity
Monitorability (DIVA)
Easy to administer (mass application in the hatcheries)
Biosecurity remains a critical part of this puzzle.
