This phase of the development of the vaccine was attributed to Louis Basudeb (Louis Pasteur) (Figure 2) in the late nineteenth Century in the field of vaccine development and the pioneering role of excellence. The great contribution of Pasteur, known as the father of vaccine, lies in that he chooses the pathogenic microorganism with strong immunogenicity to be cultured, physically and chemically deactivated, and then purified. The virulent strain of inactivated vaccine is generally virulent, but the attenuated and attenuated strain also has good immunogenicity, such as poliomyelitis inactivated vaccine produced by Sabin (Sabin) attenuated strain. Attenuated live vaccine is made by artificial directional mutation, or from natural selection of highly virulent or non-toxic living microorganism, and inoculated with it, so as to prevent infectious diseases.

At the end of the nineteenth Century, Koch (Koch) invented a method to isolate bacterial cultures on a solid medium, which laid the foundation for Pasteur to develop a vaccine. Pasteur first discovered that the growth toxicity of bacteria on the artificial medium decreased for a long time, such as Vibrio cholerae after two weeks. And the important thing is that if fresh Vibrio cholerae are used to attack the injected chickens, none of them will have cholera. Pasteur believes that this is due to the reduced virulence of Vibrio cholerae in the old culture, but the immunogenicity still exists, which makes chickens produce immunity against Vibrio cholerae. In this theory, two weeks after the culture of Bacillus anthracis in the environment of 42~43 C, a live attenuated anthrax vaccine was made.

In May 5, 1881, Pasteur chose 24 sheep, 1 goats and 6 cattle. The animals were vaccinated with anthrax vaccine and were immunized two times after 12 days with anthrax vaccine. In May 31st, the experimental group and the control group were attacked by pathogenic Bacillus anthracis. The results were as follows: (1) all sheep and goats died in the control group, 2 cows died and 4 cows were in serious condition. 2. Only 1 sheep died in the experimental group. The experimental results show that the anthrax vaccine has a protective effect on animals. Since the first formal use of the live attenuated anthrax vaccine in 1881, 85000 sheep were immunized at the beginning of 1882, and an unprecedented immune protection effect was achieved.

呢一階段疫苗嘅發(fā)展歸功于路易·巴斯德（Louis Pasteur）于十九世紀(jì)末喺疫苗研制領(lǐng)域嘅先鋒作用同貢獻。被譽為疫苗之父嘅巴斯德嘅偉大貢獻在于：佢選用免疫原先性強嘅病原微生物經(jīng)培養(yǎng)，用物理或者化學(xué)方法將其滅生之后，再經(jīng)純化做。冇生疫苗使用嘅毒種一般系強毒株，但使用減毒嘅弱毒株都有良好嘅免疫原先性，如用薩賓（Sabin）減毒株生產(chǎn)嘅脊髓灰質(zhì)炎滅生疫苗。減毒生疫苗系采用人工定向變異嘅方法，或者喺自然界篩選出毒力高度減弱或者基本無毒嘅工作嘅微生物做疫苗，并以此畀人接種而去到預(yù)防惹病嘅目的。

喺十九世紀(jì)末，科赫（Koch）發(fā)明咗喺固體培養(yǎng)基上分離架嘛培養(yǎng)細菌物嘅方法，應(yīng)該法為巴斯德研制疫苗奠定咗基礎(chǔ)。巴斯德首先發(fā)現(xiàn)細菌喺人工培養(yǎng)基上長時間生長咗毒減弱，如放置兩星期后嘅雞霍亂弧菌，以此菌畀雞仔打針后唔使雞致病。而且重要嘅系：如果而且用新鮮嘅霍亂弧菌攻擊啲已打針嘅雞仔，佢哋都唔會發(fā)生霍亂。巴斯德認(rèn)為呢系由于陳舊培養(yǎng)物中雞霍亂弧菌嘅毒力減低，但免疫原先性依然系存在，因而令雞仔惹咗針對霍亂弧菌嘅免疫力。以此理論巴斯德將炭疽桿菌喺42~43℃嘅環(huán)境下培養(yǎng)兩星期后，做人工減毒炭疽生疫苗。

1881年5月5日巴斯德選擇24頭綿羊、1頭山羊同6只牛實驗。用炭疽疫苗接種啲動物，隔12天后而且用炭疽疫苗二次加強免疫。5月31日對實驗組同對照組采用致病嘅炭疽桿菌攻擊，結(jié)果系：①對照組綿羊同山羊全部死亡，2只牛死亡同4只牛病情傷；②試驗組僅有1頭綿羊死亡。實驗說明炭疽結(jié)果疫苗對動物有保護作用。自1881年減毒炭疽生疫苗*次正式使用，到1882初，公司有85000頭綿羊畀免疫，并獲得咗*嘅免疫保護效果。
