SPECIAL WARNINGS
Vaccine virus spreads from bird to bird. In a study in highly
susceptible Rhode
Island Red birds, vaccine virus was shown to increase in virulence
after ten
passages.
Maternally derived antibody (MDA) can interfere with the development
of active
immunity. Where it is likely that recent field infection or
vaccination of the
parent flock has stimulated a high antibody titre and consequently a
high level
of MDA, the timing of the vaccination programme should be planned
accordingly.
