They have had a prominent place in the history of medicine, from Pasteur's pioneering 19th-century work with cattle (the first effective bacterial vaccine and the second effective vaccine ever) to the controversial late 20th century use of a modern product to protect . Inactivated vaccines. Vaccines can be divided into three types: subunit vaccines, inactivated microorgan-isms, and live attenuated microorganisms. The viruses weakened but not killed. The Jynneos vaccine is produced by Bavarian Nordic, a small company in Denmark. Live attenuated vaccines such as measles, rubella, mumps or yellow . Live-attenuated vaccine . Miyairi I, Ishikura K, Ogura M, Shoji K, Funaki T, et al. There's one exception: a nasal mist flu vaccine is made with live, "attenuated" viruses, says the US Centers for Disease Control and Prevention (CDC). Live attenuated influenza viruses (LAIV) usually have a broader protection than the killed vaccine and they are cheaper and easier to administer. Anthrax vaccines are vaccines to prevent the livestock and human disease anthrax, caused by the bacterium Bacillus anthracis..
