The following are notable events in the Timeline of immunology:
1550 BCE – The Ebers papyrus recommends placing a poultice on a tumor and then making an incision, which would induce infection and cause regression of the tumor.[1]
1829 – Another case of spontaneous remission of breast cancer after a patient refused surgery and the tumor ruptured, became infected and during a febrile illness with purulent discharge, it shrunk and disappeared after a few weeks. (Guillaume Dupuytren)[4][5][6]
1837 – Description of the role of microbes in putrefaction and fermentation (Theodore Schwann)
1838 – Confirmation of the role of yeast in fermentation of sugar to alcohol (Charles Cagniard-Latour)
1850 – Demonstration of the contagious nature of puerperal fever (childbed fever) (Ignaz Semmelweis)
1857–1870 – Confirmation of the role of microbes in fermentation (Louis Pasteur)
1867 – Aseptic practice in surgery using carbolic acid (Joseph Lister)
1868 – Busch discovered that a sarcoma patient being surgically intervened to remove the tumor, after being exposed to a patient suffering from erysipelas, got a skin infection and her tumor disappeared. He inoculated some other cancer patients with many successes.[7][4]
1876 – Demonstration that microbes can cause disease-anthrax (Robert Koch)
1878 – Confirmation and popularization of the germ theory of disease (Louis Pasteur)
1880 – 81 Theory that bacterial virulence could be attenuated by culture in vitro and used as vaccines. Used to make chicken cholera and anthrax "vaccines" (Louis Pasteur)
1882 – Identification of Streptococcus pyogenes as the causative agent of erysipelas (Friedrich Fehleisen). He repeats Busch experiments inoculating cancer patients with eryisipelas, noting tumor regression in many of them.[8]
1883–1905 – Cellular theory of immunity via phagocytosis by macrophages and microphages (polymorhonuclear leukocytes) (Elie Metchnikoff)
1885 – Introduction of concept of a "therapeutic vaccination". Report of a live "attenuated" vaccine for rabies (Louis Pasteur and Pierre Paul Émile Roux).
2010 – The first autologous cell-based cancer vaccine, Provenge, is approved by the FDA for the treatment of metastatic, asymptomatic stage IV prostate cancer.
2010 – First immune checkpoint inhibitor, ipilimumab (anti-CTLA-4), is approved by the FDA for treatment of stage IV melanoma
2011 – Carl H. June reports first successful use of CAR T-cells expressing the 4-1BB costimulatory signaling domain for the treatment of CD19+ malignancies
2014 – A second class of immune checkpoint inhibitor (anti-PD-1) is approved by the FDA for the treatment of melanoma. Pembrolizumab and nivolumab are approved within months of each other.
2016 – The role of dendritic cell expressed CTLA-4 in Th immune polarization is first described
2016 – A third class of immune checkpoint inhibitor, anti-PD-L1 (atezolizumab), is approved for the treatment of bladder cancer
2017 – First autologous CAR T-cell therapy tisagenlecleucel approved for the treatment of pediatric B-ALL; second autologous CAR T-cell therapy axicabtagene ciloleucel (Yescarta) is approved.
2020 – The first mRNA vaccines (BNT162b2, mRNA-1273), are developed for SARS-CoV-2 infection; this new technology completed design, testing, and emergency approval in under one year.
