the perineal zone or the udder.
The ID device supplied by the manufacturing authorisation holder or other suitable
needle-free device able to administer 0.2 ml doses (injection stream diameter of
0.25-0.30 mm and a peak force of injection of 0.9-1.3 N) should be used.
Aseptic injection techniques should be observed to avoid introduction of
contamination during vaccine administration.
Reconstitute the vaccine with the corresponding solvent:

If the solvent is refrigerated, it should be allowed to warm up to a temperature
between 15 ºC to 25 ºC before reconstitution of the freeze-dried powder.
Peel the aluminium capsule off the bottle containing the solvent and aspirate in
order to remove a certain volume of the contents. Then inject this volume of
solvent into the vial containing the freeze-dried powder. Shake until the freeze-
dried powder is completely dissolved. Once reconstituted, withdraw all the
suspension obtained from the vaccine vial and inject it into the vial containing the
remaining solvent. Shake well before use. The reconstituted vaccine is a
homogeneous reddish solution. Avoid the introduction of contamination during
reconstitution and use. Use only sterile needles and syringes for administration
The following doses and administration methods should be used:
Pigs from 3 weeks of age
2 ml via intramuscular injection or 0.2 ml via intradermal administration.
Breeding females:
2 ml via intramuscular injection or 0.2 ml via intradermal administration. A single
vaccination should be administered once in each reproductive cycle for protection
during the subsequent pregnancy.
In gilts, administer one injection of the reconstituted vaccine per animal 4 weeks
before mating.
In sows, administer one injection of the reconstituted vaccine per animal:

mating) or
o
PRRS-naïve sows should not be vaccinated during pregnancy.
For simultaneous use with ERYSENG PARVO in breeding females from 6 months
of age, the mixed administration of UNISTRAIN PRRS and ERYSENG PARVO
should only be used when vaccinating animals prior to mating.
The following instructions should be used: the contents of a single vial of
UNISTRAIN PRRS should be reconstituted with the contents of a single vial of
ERYSENG PARVO in the same way as described for reconstitution with solvent.
A single dose (2 ml) of the mixed vaccines should be injected within a period of 2
hours via intramuscular use.
