Merilym 3 Suspension for Injection for Dogs (10 Dose).
Suspension for injection.
Pinkish to white fluid containing white sediment that disperses easily when the content is shaken.
Composition of one dose (1ml): Active substances:
Inactivated Borrelia burgdorferi sensu lato:
Borrelia garinii RP = 1*
Borrelia afzelii RP = 1*
Borrelia burgdorferi sensu stricto RP = 1*
*RP = Relative potency (ELISA test) compared with the reference serum obtained after vaccination of mice with a vaccine batch that has successfully passed the challenge test in the target species.
Aluminium (as hydroxide) 2 mg
Formaldehyde max. 0.5 mg/ml
For active immunisation of dogs from 12 weeks of age, to induce an anti-OspA response against Borrelia spp. (B. burgdorferi sensu stricto, B. garinii and B.afzelii).
Onset of immunity: 1 month after primary vaccination.
Duration of immunity: one year after primary vaccination.
Reduction of Borrelia transmission was only investigated under laboratory conditions, following a challenge with field ticks (collected from a region known to be affected by Borrelia). Under these conditions, it was shown that no Borrelia could be isolated from the skin of vaccinated dogs, while Borrelia were isolated from the skin of non vaccinated dogs.
Reduction of transmission of Borrelia from the tick to the host has not been quantified, and no correlation has been established between a specific level of antibodies and reduction of Borrelia transmission. The efficacy of the vaccine against an infection that leads to the development of clinical disease has not been studied.
Dosage and administration
1 ml from 12 weeks of age by subcutaneous injection. Shake the vial well before use and administer according to the following schedule:
Primary vaccination: administer two doses separated by an interval of 3 weeks.
Revaccination: Annual revaccination with a single dose is recommended to maintain immunity although this schedule has not been investigated.
Vaccination should be carried out prior to periods of increased tick activity, allowing sufficient time for the immune response to vaccination to develop fully prior to expected tick exposure.
