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

• f 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)

Vaccines

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 Authorities

Number of Vaccinations Dates

Vaccination Campaign (August 2015- Dec 2016)

Number of Vaccinations per Day in Greece 467 days of Vaccination / ~ 690.000 vaccinations Vaccinations per day 1.462 mean (2min, 7.507 max)

Vaccination Coverage Dec 2016

50-69% coverage 70-94% coverage 95-100% coverage 50-69% coverage 70-94% coverage 95-100% coverage Less than 50%

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
• utside 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
