ReproCyc PRRS EU Lyophilisate and Solvent for Suspension for Injection for Pigs

Vaccinate healthy animals only.
Precautions should be taken to avoid the transfer of the vaccine virus within
the herd, e.g. from positive animals to naïve animals.

Special precautions for safe use in the target species:
The vaccine strain may spread up to 5 weeks after vaccination to unvaccinated
animals in contact but without any clinical consequence. Vaccinated animals
may excrete the vaccine strain by faecal excretion. The potential excretion of the
vaccine strain in the urine of vaccinated animals has not been investigated.
The vaccine strain has been detected in new-born piglets (blood, lung
samples) when vaccinating gilts during last third of gestation but without
any clinical consequence.
Care should be taken to avoid spread of vaccine virus from vaccinated animals
to unvaccinated animals that should remain free from PRRS virus.
Vaccination should aim to achieve a homogenous immunity in the target
population at farm level.
PRRS virus-naïve breeding animals (e.g. replacement gilts from PRRS virus-
negative herds) which are introduced into a PRRSV-infected herd should be
vaccinated prior to first insemination. Vaccination should preferably be done in
a separated quarantine unit. A transition period should be respected between
vaccination and moving the animals to the breeding unit. This transition period
should be longer than the shedding phase of the PRRS MLV vaccine following
vaccination.
Do not routinely rotate two or more commercial PRRS MLV vaccines based on
different strains in a herd. A PRRS vaccine based on the same strain (strain
94881) and authorised for the immunisation of pigs from 17 days of age until the
end of fattening and older can be used on the same farm.
In order to limit the potential risk of recombination between PRRS MLV vaccine
strains of the same genotype, do not use different PRRS MLV vaccines based
on different strains of the same genotype on the same farm at the same time.
In the case of transitioning from one PRRS MLV vaccine to another PRRS MLV
vaccine, a transition period should be respected between the last administration
of the current vaccine and the first administration of the new vaccine. This
transition period should be longer than the shedding period of the current
vaccine following vaccination.
Special precautions to be taken by the person administering the veterinary
medicinal product to animals:
In case of accidental self-injection, seek medical advice immediately and show
the package leaflet or the label to the physician.
Special precautions for the protection of the environment:
Not applicable.
