Overview of the Epizootic
Decision on Emergency Vaccination Since the beginning of the epizootic, emergency vaccination was
decided and European Commission was informed Evros Area historically suffers from animal diseases crises (e.g. Sheep Pox in 2013-2014, BT 2014 e.t.c) Devastating effects for the local farming industry with negative impact to
local Society and Economy
High costs for the State : Cost of control measures Stamping out, Vaccination, Compensation Cost for Veterinary Services The involvement of vectors on the transmission of the disease complicates
the control: environmental conditions (wetlands), type of production (free grazing beef cattle)
Unclear if the stamping out policy alone was sufficient to stop the disease spread
“Each rule has its exception” 2 rules with 2 exceptions
Legislative limits on Vaccination
Dir. 92/119 artc.19: Preventive Vaccination in EU is not allowed
Dir. 92/119 artc.19: Emergency Vaccination may implemented as a supplementary control measure taken when the disease broke out
No marketing authorization of LSD vaccines in Greece or in EU
Dir. 2001/82 artc. 5: Veterinary medicinal products are not allowed to be placed on the market of a MS, unless a marketing authorization has been granted by the CA of that MS.
Dir. 2001/82 artc. 8: In the event of serious epizootic diseases, Member States may provisionally allow the use of immunological veterinary medicinal products without a marketing authorization, in the absence of a suitable medicinal product and after informing the Commission of the detailed conditions of use.
Homologous live attenuated virus vaccines: “Lumpy Skin Disease Vaccine for Cattle”, Onderstepoort Biological Products,
OBP, South Africa (Neethling type) 2 ml/per dose, subcutaneous “Lumpyvax” by MSD Animal Health-Intervet, South Africa (SIS type) 1 ml/per dose, subcutaneous Compulsory vaccination of all susceptible species (cattle, buffaloes)
Vaccination from age 0 according to the instructions (animals from unvaccinated cattle)
28 days standstill of vaccinated animals (3 weeks to full disease protection +1
week to cover the maximum disease incubation period)
Annual booster vaccination An electronic application (online database) has been developed for
registration of vaccinated animals and farms (connected with the central data base of Reg. 1760/2000)

Vaccination Plan Vaccination Started: on 5/09/2015 RU Evros after the first confirmation of LSD: 20/08/2015 RU Evros At the beginning around the outbreaks in affected Regional Units Xanthi, Rodopi, Kavala, Chalkidiki, In October 2015 creation of buffer zone in free areas and progressive
extension according to the availability of the vaccines 1st Priority: Thessaloniki, Drama, Serres, Kilkis, 2nd Priority: Imatia, Pella, Pieria
In May 2016 when the disease crossed the buffer zone: The Vaccination of total mainland firstly and the islands later decided Vaccination Campaign is under the official control of the Veterinary

Adverse Effects and Reactions to the Vaccine
Common expected findings (Information provided by vets and farmers)
• Oedema and pain around the point of injection • Local reactions with nodules around the point of injection • Dairy Cattle seems to be more sensitive to develop local reactions • Drop of milk production • Abortions
Cases of generalized symptoms
During 2015- 2016 221 outbreaks have been confirmed 69 concerned vaccinated animals
62 outbreaks suspicion was notified less than 28 days post vacc.
4 outbreaks, the suspicion notified 30 to 52 post vacc. 1 outbreak 5 months post vacc (1 infected / 379 animals)
2 outbreaks concerned calves coming from vaccinated cattle
3 out of 69 outbreaks vaccine strain was indentified, all the others were field strains
Stamping out was implemented to all bovine animals in the herds (pick period of the epizootic, risk to wait 21 days the results of sequencing and phylogenetic analysis)
2 suspicions : the vaccine strain identified and the measures lifted
The analysis of data are still in progress
Practical Aspects-Difficulties-Limitations Official Control and Supervion by the Veterinary Authorities
The whole procedure of vaccination is under the control of the official veterinary authorities (delivery at the airport, storage, distribution, vaccination, destroy of residual quantities)
High costs for Veterinary Authorities Managerial difficulties, coordination, control Strict Measures for vaccinated animals : Restrictions of the movements: animals were not allowed to be dispatched
outside vaccination area 28 days post vaccination standstill Restriction to trade activities of live bovine animals, their products, animal by-
products Unwillingness of stakeholders to implement vaccination Uncertainties and lack of information complicated the decision making
Challenges for the future Effectiveness of Vaccination
Experience shows that vaccination is the only effective measure against the disease especially preventive vaccination But to what extend ? When ?? and for how long ? According to which criteria? Is the absence of the outbreaks a verification of the absence of the LSD? Subclinical Cases, Mild Clinical Signs, Animals not develop Immunity, Under notification Clinical examination is the only available tool to estimate in large scale the situation on the field Scientific Research
• effective and safe vaccines • vaccines support DIVA protocol • vaccine vs field strain:Greek NRL: DIVA Real Time PCR • presence and excretion of vaccine strain • immune response to vaccination • duration of immunity • immunity in calves • Viraemia in vaccinated animals
