Reporting adverse events is important. It allows continuous safety monitoring of a
veterinary medicinal product. Reports should be sent, preferably via a veterinarian,
to either the marketing authorisation holder or the national competent authority via
the national reporting system. See also section 16 of the package leaflet for contact
details.

Vaccinate healthy animals only.
The potential impact of maternally derived antibodies on efficacy of vaccination has
not been established.

Issued: March 2024
AN: 02172/2022
The product is a live attenuated vaccine. Antimicrobials active against Mycoplasma
spp. should not be given 15 days before or after vaccination or during the two-dose
basic vaccination scheme as they could interfere with vaccine efficacy. Within these
time frames, and in the situation where a clinical condition requires the prescription
of antimicrobials, preference should be given to those with no anti-Mycoplasma spp.
activity.

Special precautions for use in animals
The safety of the veterinary medicinal product has not been established in breeding
bulls.
The live attenuated Mycoplasma bovis vaccine strain may disseminate into synovial
fluid, lymph node, middle ear, conjunctiva, tonsil and lung tissue after vaccination.
In a laboratory study conducted using a dose 7-fold higher than the maximum
bacterial content, nasal shedding was observed for at least 9 days post-vaccination
in an animal vaccinated through intramuscular and subcutaneous routes. However,
the vaccine strain did not spread to in-contact control animals.
Distinguishing between field strains and the vaccine strain of M. bovis can be
performed by whole genome sequencing tests. Additional information to differentiate
the vaccine strain from field strains is available upon request from the marketing
authorisation holder.
Special precautions to be taken by the person administering the veterinary medicinal
product to animals
No special precautions to be taken by the person administering the veterinary
medicinal product to animals are necessary as M. bovis is not considered to present
a risk to healthy humans. However, in case of development of adverse reactions
following 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.
Other precautions
Not applicable.

No information is available on the safety and efficacy of this vaccine when used with
any other veterinary medicinal product. A decision to use this vaccine before or after
any other veterinary medicinal product therefore needs to be made on a case by
case basis.

Store and transport refrigerated (2 C – 8 C).
