  • The Use of Live Vaccine for Vaccination of Human Beings Against Brucellosis in the USSR
    Bull. Org. mond. Santeh 1961 2 85-89 Bull. Wld HIth Org. J The Use of Live Vaccine for Vaccination of Human Beings against Brucellosis in the USSR P. A. VERSHILOVA, M.D.1 The great majority of human brucellosis cases in the USSR are caused by contact with infected sheep and goats. Extensive action has been taken to prevent human infection and to reduce the incidence among farm animals, the main prophylactic measure in recent years being vaccination with live brucellosis vaccine. The author summarizes the steps leading to the development of a satisfactory vaccine and gives a brief description of the method of preparation. Discussing the results obtained, she states that there has been a nearly 60 %,0 reduction in the number of human cases over the period 1952-58. The subcutaneous route of administration is usually resorted to, but preliminary figures suggest that cutaneous vaccination is equally effective immunogenically, although in persons who have sujJeredfrom active brucellosis it causes strong reactions and may lead to exacerba- tion of the disease. Research is going forward into the development ofa cutaneous vaccine capable ofgeneral use. INTRODUCTION and at the same time measures of prophylaxis have been organized to prevent human infection. Since Epizootiological and epidemiological data now 1953-54, wherever there is a risk of human infection available show that brucellosis is distributed quite with brucellosis of goats and sheep, the main pro- widely in many countries.

  • The Landscape of Vaccines in China: History, Classification, Supply, and Price
    Zheng et al. BMC Infectious Diseases (2018) 18:502 https://doi.org/10.1186/s12879-018-3422-0 RESEARCHARTICLE Open Access The landscape of vaccines in China: history, classification, supply, and price Yaming Zheng1, Lance Rodewald2, Juan Yang3, Ying Qin1, Mingfan Pang1, Luzhao Feng1 and Hongjie Yu1,3* Abstract Background: Vaccine regulation in China meets World Health Organization standards, but China’s vaccine industry and immunization program have some characteristics that differ from other countries. We described the history, classification, supply and prices of vaccines available and used in China, compared with high-and middle-incomes countries to illustrate the development of Chinese vaccine industry and immunization program. Methods: Immunization policy documents were obtained from the State Council and the National Health and Family Planning Commission (NHFPC). Numbers of doses of vaccines released in China were obtained from the Biologicals Lot Release Program of the National Institutes for Food and Drug Control (NIFDC). Vaccine prices were obtained from Chinese Central Government Procurement (CCGP). International data were collected from US CDC, Public Health England, European CDC, WHO, and UNICEF. Results: Between 2007 and 2015, the annual supply of vaccines in China ranged between 666 million and 1,190 million doses, with most doses produced domestically. The government’s Expanded Program on Immunization (EPI) prevents 12 vaccine preventable diseases (VPD) through routine immunization. China produces vaccines that are in common use globally; however, the number of routinely-prevented diseases is fewer than in high- and middle- income countries. Contract prices for program (EPI) vaccines ranged from 0.1 to 5.7 US dollars per dose - similar to UNICEF prices.

  • Results of Pre-Clinical and Clinical Tests of Organic Hydroxyapatite As Adjuvant of Bacterial Vaccine

Vavilov, Russia, 410012, Saratov, Teatralnaya square, Russia. Abstract | Vaccination continues to be one of the most effective ways to protect against infectious diseases; therefore, there is a need to develop new vaccines that have low cost and are used either once or for long periods of time.The current study aims to test organic hydroxyapatite in bacterial vaccines on laboratory and farm animals and determine its adjuvant and immunogenic properties. In pre-clinical tests, white mongrel mice weighing 18-20g and rats weighing 250-300g were used. Adjuvant (organic hydroxyapatite) separately and as part of vaccines was administered subcutaneously, intraperitoneally and intramuscularly at a dose of 0.5 ml. Clinical tests of adjuvant were carried out on Holstein-Friesian cows and calves. Experimental vaccines were used: 1) a split-conjugated vaccine against animal brucellosis (as antigens it included the components of brucella (Br. Abortus); 2) a vaccine against mastitis of cows. Results showed that PhA, neutrophils and monocytes in the blood smears of the control group were 1.4 times lower, and twice as much compared to the vaccine without the adjuvant. The maximum PhI(FI) was observed in animals immunized with a split-conjugated vaccine against brucellosis of animals with the adjuvant. The disappearance of vaccine antibody titer in the blood after 30 days was stated, which is positive in the diagnosis of brucellosis.

Objective: Many eukaryotic plasmid vectors are being used in setting up DNA vaccines which may show different efficiencies in same conditions. This is important in designing the vaccines and immunization strategies. We looked into the probable differences of immune responses induced by different eukaryotic DNA plasmid vectors (pcDNA3.1 and pVAX1) harboring the same Omp31 gene of B. melitensis. Materials and Methods: Female BALB/c mice were immunized with pcDNA-omp31 and pVAX-omp31 and further boosted with recombinant Omp31. Subclasses of specific serum IgG against the rOmp31 were measured by ELISA. Cytokines responses to rOmp31 in Splenocyte cultures of the immunized mice were evaluated by measuring the production of IL- 4, IL-10, IL-12 and IFN-γ.

    INTRODUCTION The first disease for which a bacterial agent was found to be the cause was anthrax (Greek meaning coal for the characteristic eschars found on the skin) (11,19). The disease is thought to have been the cause of the fifth and sixth plagues that attacked the livestock and people of Egypt in Exodus 9 (5,11,17). Casimir Davaine first isolated the bacterium, Bacillus anthracis, in 1850 (11). In 1876, Robert Koch developed a method for culturing pure B. anthracis and in 1881, Louis Pasteur created the first major vaccine against the disease in livestock (5,11). Despite the existence of vaccines against the disease since the 1870’s, anthrax remains a serious threat to livestock and even humans in the developing countries of Asia, Africa and South America (19). B. anthracis, the causative bacterial agent of anthrax, is believed to be part of the biological arsenals of at least ten nations. With the current world environment and the unpredictable threat of terrorism, it would seem prudent to include biological warfare defense measures into our national defense arsenals (8,11). The bacteria in the genus Bacillus are characterized as large, gram-positive, rod- shaped organisms (31). B. anthracis occurs singly or in pairs in tissue, and in culture appear in long strings giving a classic “boxcar” look. The anthrax bacterium is never motile (19). B. anthracis is a spore-forming bacterium whose spores can survive in dry form for indefinite periods of time and then be released into the atmosphere with the capability of causing disease (8). Spore formation occurs after host death.

Antibiotic prophylaxis with doxycycline and rifampin for six weeks was indicated, but rifampin was discontinued after 10 days due to gastrointestinal in- tolerance. Despite prophylaxis, the patient seroconverted after 30 days, but was asymptomatic and did not require additional antibiotic therapy. Post-exposure prophylaxis of Brucella is not free from side effects and asymptomatic seroconversion can occur despite prophylaxis.

Bovine brucellosis is a zoonotic disease that has considerable economic impact on the market of products such as meat and milk. As Brazil has one of the largest cattle herds in the world, this disease is a significant agricultural and public health concern. In 2001, Brazil launched the National Program of Control and Eradication of Animal Brucellosis and Tuberculosis. This program included the vaccination of 3-8 month old calves using the smooth and attenuated S19 strain, as well as monitoring with serological tests. There have been reports of excretion and persistence of S19. In this context, the objective of this study was to monitor the persistence of the S19 vaccine strain in blood samples from vaccinated calves. Seroconversion was investigated to evaluate the vaccine immunogenicity. PCR assays of blood and serum were run at at: "day zero" (before vaccination), 1 to 15 days after vaccination and every month until 12 months, totaling 28 collections for each of 10 calves.
