| 1955 | The Cutter polio vaccine incident began on April 25, 1955, when polio was reported in a vaccine recipient. One day later, five more cases were reported. All cases had received vaccine produced by Cutter Laboratories. Polio was reported in 94 vaccinees and in 166 close contacts of vaccinees. On April 27, the Laboratory of Biologics Control requested that Cutter Laboratories recall all vaccine and the company did so immediately. On May 7, the Surgeon General recommended that all polio vaccinations be suspended pending inspection of each manufacturing facility and thorough review of the procedures for testing vaccine safety. The investigation found that live polio virus had survived in two batches of vaccine produced by Cutter Laboratories. In 1955, as a result of the Cutter Incident, the Laboratory of Biologics Control was raised to division status within NIH, to strengthen and expand its biologics control function. Large-scale polio vaccinations resumed in the fall of 1955. |

| 1930 | The Hygienic Laboratory changed its name to the National Institute (singular) of Health and authorized the establishment of fellowships for biological and medical research. |
| 1930 | Cell culture was developed and shown to be able to grow virus, thus paving the way for the subsequent production of viral vaccines. |
| 1928 | The first iron lung was used to preserve breathing function in patients with acute polio. |
| 1927 | Bacille Calmette-Guerin (BCG) vaccine was first used in newborns, having been developed by Albert Calmette and Camille Guéérin in 1921. BCG (live-attenuated Mycobacterium bovis BCG) represented the only vaccine against tuberculosis. It has become the most widely administered of all vaccines in the WHO Expanded Programme for Immunization, but has been estimated to prevent only 5% of all potentially vaccine-preventable deaths due to tuberculosis. |
| 1923 | Diphtheria toxoid was licensed; prepared from the inactivated bacterial toxin that has lost its toxicity but retains its antitoxin producing properties. In 1924, Gaston Ramon discovered diphtheria toxoid. Along with the discovery of antitoxins, Ramon uncovered the role of adjuvant substances of immunity. |
| 1918 | The "Spanish flu" influenza pandemic was responsible for at least 50 million deaths worldwide, with about 675,000 deaths in the U.S. This virus was unusual because it spread so quickly, was so deadly, and exacted its worse toll among the young and healthy. About one-third of the world's population (~500 million people) were infected. |
| 1915 | Pertussis vaccine, a suspension of inactivated Bordetella pertussis cells, was licensed. Inactivated vaccines were prepared with a microorganism or virus that had been killed, usually with a chemical such as formaldehyde. |
| 1914 | Typhoid vaccine was first licensed in the U.S. |
| 1914 | Rabies vaccine was first licensed in the U.S. |
| 1914 | Tetanus toxoid was introduced following the development of an effective therapeutic serum against tetanus by Emil Von Behring and Shibasaburo Kitasato. |
| 1908 | The first county health departments in the U.S. were formed. |
| 1906 | The Pure Food and Drugs Act was formed, prohibiting interstate commerce in misbranded and adulterated foods, drinks, and drugs. |
| April 5, 1902 | The Biologics Control Act was formed. It included the regulation of vaccine and antitoxin producers and required both licensing and inspections of manufacturers. The standards imposed by the 1902 Act resulted in bankruptcy for one-third of the companies manufacturing antitoxins and vaccines while benefiting the manufacturers already in compliance. Ten firms held licenses with the Laboratory of Hygiene following the 1902 Act. |
| 1901 | In St. Louis, 13 children died of tetanus-contaminated diphtheria antitoxin. In the autumn of 1901, nine children in Camden, New Jersey, died from tainted smallpox vaccine. Efforts to ensure the purity of biological treatments by government oversight followed with the Biologics Control Act of 1902. |
| 1901 | The first Nobel Prize for Physiology and Medicine was awarded to Emil von Behring for his work on the development of a diphtheria antitoxin (later known as antiserum). |
| 1897 | Plague vaccine was introduced, following the preparation of anti-plague horse serum at the Pasteur Institute by Alexandre Yersin. After demonstrating protection from disease in immunized animals, Yersin went to China with the vaccine to protect humans during a plague epidemic. |
| 1896 | Cholera and typhoid vaccines were first developed. |
| 1893 | City and state public health departments began mass production of diphtheria antitoxin, following its introduction in European laboratories. |
| 1888 | The Pasteur Institute was established as a rabies treatment center as well as an infectious diseases research and training institute. |
| 1888 | The diphtheria toxin was discovered by Emile Roux. Passive serum therapies were developed through the scientific contributions of many, including Emil Von Behring who developed the first effective therapeutic serum against diphtheria and Paul Ehrlich who developed enrichment and standardization protocol, which allowed for an exact determination of quality of the diphtheria antitoxins. |
| 1887 | Joseph Kinyoun established one of the country's first bacteriological laboratories in the Marine Health Service Hospital on Staten Island, NY. He was director of the Laboratory of Hygiene, which moved to Washington, D.C., in 1891. Kinyoun brought the latest techniques such as the procedure for preparing diphtheria antitoxin back from his visits to Europe. |
| 1885 | Louis Pasteur first used rabies vaccine in humans. |
| 1884 | The first live attenuated viral vaccine (rabies) was developed by Louis Pasteur, using dessicated brain tissue inactivated with formaldehyde. |
| 1882 | Robert Koch identified the tubercle bacillus as the cause of tuberculosis, subsequently called Koch's bacillus. |
| 1881 | Louis Pasteur and George Miller Sternberg almost simultaneously isolated and grew the pneumococcus organism. |
| 1879 | Louis Pasteur created the first live attenuated bacterial vaccine (chicken cholera) |
| 1877 | Louis Pasteur proposed The Germ Theory of Disease. |
| 1798 | Edward Jenner published his work on the development of a vaccination that would protect against smallpox. Two years earlier, in 1796, he had first speculated that protection from smallpox disease could be obtained through inoculation with a related virus, vaccinia or cowpox. He tested his theory by inoculating eight-year-old James Phipps with cowpox pustule liquid recovered from the hand of a milkmaid, Sarah Nelmes. |
| 1798 | The Marine Health Service was established in 1798 as the nation's first public health agency. It provided hospital care for merchant seamen and protected port cities against diseases such as smallpox, cholera, and yellow fever. |
| 1721 | Variolation was introduced to Great Britain. |
| 1100s | The variolation technique was developed, involving the inoculation of children and adults with dried scab material recovered from smallpox patients. Variations of variolation have been noted in Turkey, Africa, China, and Europe. |
| 400 BC | Hippocrates described mumps, diphtheria, epidemic jaundice, and other conditions |
