THE ROLE AND PLACE OF VACCINE IN THE SYSTEM OF PREVENTION AND STRUGGLE AGAINST FOOT-AND-MOUTH DISEASE
The article analyzes the prophylactic drugs against foot-and-mouth disease of various manufacturers, which are present in the veterinary market, the effectiveness of their use, revealed the causes of postvaccinal immunity breakthrough in some examples. Presented historical data on the creation of anti FMD vaccines. The measures, which are carried out and applied in CIS countries against foot and mouth disease, are analyzed. Introduction. It is known that FMD refers to so-called biological threats, namely, a group of diseases that are united under the term "zoonoses" that affect animals and humans. The disease causes significant economic losses both to the farms where it arose and to the country as a whole. Unfortunately, and still on our planet in many regions of the world and today there are outbreaks of this disease. The pathogen is a viral nature and can spread rapidly over long distances. One of the means of prevention is the use of preventive vaccines. All currently available vaccines are inactivated immunobiological drugs. There are more than 20 manufacturers of anti-foot-and-mouth disease vaccines, and different vaccine formulations are used in different regions, which must be consistent with the serotypes of the virus circulating in the area. It is important to quickly identify and determine the antigenic and genetic relevance of the strains of the virus that caused the disease, since the virus often changes its properties (mutants) to properly select the necessary vaccines. Often, the question arises as to the effective selection of prophylactic drugs for the acquisition and creation of a prophylactic reserve in countries free from the disease. This question is very complicated and important. Difficult because it is difficult to predict the possible skidding on the territory of one or another strain of the foot-and-mouth disease virus. To do this, it is necessary to conduct continuous monitoring of the epizootic situation in neighboring countries, to know the circulation of various serological types of foot and mouth disease virus, which are currently known to 7 (or more than 80 variants of the virus), their ecology, strain differences, to analyze possible ways of distribution, to make predictive models of possible course of events for pathogen penetration into the country. When conducting laboratory tests, it is imperative to determine the type and variant of the foot-and-mouth disease virus that caused the disease. This is important for the selection of vaccines. All this is necessary to make the correct management decisions of the state veterinary service.
The purpose of the work. Analyze the use of vaccines in different countries and their effectiveness, which can be valuable in making decisions on foot-and-mouth disease vaccine prophylaxis.
Materials and methods of research. Applied analytical and statistical research methods.
Results of research and discussion. The measures of struggle and prevention of FMD in different countries are analyzed. The historical certificates for vaccine production are given. The presence of vaccine against foot and mouth disease in the modern veterinary market and their production has been analyzed. The reasons why vaccination is sometimes not effective is analyzed.
Conclusions and perspectives of further research: The biological threat of foot-and-mouth disease is relevant to many countries around the world. Vaccination plays an important role in preventative measures against foot-and-mouth disease, but its effectiveness depends on monitoring studies on the presence and circulation of certain serotypes of foot-and-mouth disease virus and the compliance of the vaccine composition with the epizootic situation. It is extremely important for Ukraine to monitor the epizootic situation in the world with regard to foot and mouth disease, especially in neighboring countries, as well as to create a reliable protection against foot-and-mouth disease.
