Clinical information

Poulvac MD Vac Lyophilisate and Diluent for Suspension for Injection — SPC Details

Source: VMD Summary of Product Characteristics (SPC). Last updated 26 Mar 2026.

To prevent mortality and clinical signs due to infection with Marek's
disease virus. Onset of immunity has been demonstrated from 5 days
after vaccination. No information is available on the duration of the
protection elicited by vaccination. However, experience in the field
suggests that Marek’s disease vaccine virus strains and antibody titres
persist for up to 2 years after vaccination.
One dose of 0.2 ml per chicken.
The vaccine is to be administered either by intramuscular injection in
the thigh or by subcutaneous injection in the neck to one-day-old
chickens.
Reconstitute each 1,000 doses of Poulvac MD-Vac with 200 ml of
diluent at room temperature. Remove the centre tabs of aluminium
seals on both vaccine vial and diluent bottle, leaving intact the outer
ring on both vial and bottle. Cleanse rubber stoppers with alcohol and
allow to dry. All equipment used for vaccination should be sterile and
contain no traces of detergents or disinfectants. Using a sterile needle
and syringe, insert through diluent bottle stopper and withdraw 3 ml of
diluent. Transfer by inserting through vaccine vial stopper. After slight
agitation of the vial to ensure that the vaccine has dissolved, insert
needle and withdraw entire contents into the syringe. Remove the
syringe containing all the reconstituted vaccine from vial and re-insert
into diluent bottle. Expel syringe contents into diluent. The
reconstituted vaccine is now ready for use. For administration of the
vaccine an automatic syringe with a 23 gauge x 1 inch (0.60 x 25 mm)
needle is recommended. Inject each chick intramuscularly with 0.2 ml
of vaccine, the usual site being the upper thigh, or subcutaneously in
the neck.
Use within 2 hours of reconstitution.
Do not use in sick chickens.
Do not vaccinate in an infected environment.

No local or systemic reactions have been observed following the
administration of the vaccine during safety studies. However, and in
common with other immunological products, it is expected that local or
systemic reactions may occur in a very small proportion of vaccinated
birds.
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.

vaccine can be administered on the same day but not mixed with
Poulvac IBMM, Poulvac Hitchner B1 and Poulvac Bursine 2. The
products should be given at different sites.
No information is available on the safety and efficacy of this vaccine
when used with any other veterinary medicinal product except the
