Vaccination Program for Broilers ^a

Vaccine	Age	Route	Type
Marek’s disease^b	1 day	SC	Turkey herpesvirus and SB-1 or Rispens strain for high-challenge areas
Newcastle disease	1 day or	Coarse spray	B1
	14–21 days	Water or coarse spray	B1 or LaSota
Infectious bronchitis	1 day or	Coarse spray	Massachusetts
	14–21 days	Water or coarse spray	Massachusetts
Infectious bursal disease	14–21 days	Water	Intermediate
^a This is an example of a typical vaccination program. Individual programs are highly variable and reflect local conditions, disease prevalence, severity of challenge, and individual preferences.
^b Most USA commercial broiler hatcheries use an in ovo vaccination system for Marek’s disease at 17–19 days of embryonation. Infectious bursal disease vaccine (mild strain) may be combined with Marek’s disease vaccines. Vectored vaccines in which Marek’s and fowlpox vaccines have been safely modified to carry immunizing antigens for laryngotracheitis, Newcastle disease, or infectious bursal disease are also commonly used in ovo or day-old chicks. Connecticut strain is often combined with Massachusetts. Bronchitis vaccine is usually combined with Newcastle. Other bronchitis strains such as Arkansas 99 and Florida 88 are included in some areas. Vaccinations at 14–21 days are optional. A single drinking water application for Newcastle disease/bronchitis is also common.

^a This is an example of a vaccination program. Individual programs are highly variable and reflect local conditions, disease prevalence, severity of challenge, and individual preferences. SB-1, MDV301, or Rispens strain may be combined with turkey herpesvirus in some areas. Vaccination for fowlpox and laryngotracheitis depends on local requirements. Other strains of infectious bronchitis (Connecticut, Arkansas 99, Florida 88, etc) are included in some areas.
