Liise-anne Pirofski is a Professor of Medicine, Microbiology and Immunology at Albert Einstein College of Medicine and Montefiore Medical Center. [1] She is a Member of the Association of American Physicians, and a Fellow of the American Association for the Advancement of Science, American Academy of Microbiology, American College of Physicians and the Infectious Diseases Society of America.
Pirofski grew up in Northern California, close to U.S. Route 101. [2] When she was a child she wanted to become an announcer for the San Francisco Giants. [2] At the age of sixteen she attended University of California, Berkeley. [2] [3] She studied history of art and psychology. [3] She was particularly fascinated by the different representations of the Dance of Death , an artistic genre that visualises the personification of death from all walks of life. This made Pirofski interested in the impact of disease on society. [3] During the end of her college degree she decided to pursue a career in medicine. [3] She received her Doctorate of Medicine (MD) at the Albert Einstein College of Medicine in 1982 and trained in internal medicine at Bellevue Hospital. [3] At the time the HIV/AIDS epidemic was unfolding in the United States and many patients Pirofski and her colleagues at Bellevue cared for were suffering and dying from the disease. Her experience caring for patients with HIV/AIDS, a new disease at that time, led her to pursue a career path as a physician-scientist specializing in infectious diseases. Her clinical experiences led her to see the need for more science to understand why even when powerful and antibiotics were available, like for the pneumococcus or cryptococcus, they could not prevent the recurrence of pneumococcal or mortality from cryptococcal disease [3] Her experiences during her medical training inspired Pirofski to train as a scientist focused on understanding how vaccines work and immunotherapy. [3] She trained in the laboratory of Matthew Scharff, working on the structure and function of antibodies to encapsulated pathogens. [2] She joined the faculty at the Albert Einstein College of Medicine in 1988. [4]
Pirofski is interested in innate and vaccine-induced immunity to encapsulated microbes. [5] She studies the immune response to the mycosis Cryptococcosis and the bacterium Streptococcus pneumoniae . [4] [6] She has explored antibody-based therapies for the treatment of infectious diseases. [7] In the early 2000s, in collaboration with Arturo Casadevall, Pirofski developed the ‘Damage-Response Framework’ of microbial pathogenesis; which is a theory focused on the outcome of host-microbe interaction that considers the role of both hosts and pathogens in the outcome of infectious diseases and microbial pathogenesis. [8] Pirofski was appointed chief of the division of infectious diseases at Albert Einstein College of Medicine and Montefiore Medical Center in 2006. [9]
During the COVID-19 pandemic Pirofski looked to deploy convalescent plasma, a therapy with a century long history of use in epidemics, as a treatment for COVID-19. [10] She, along with colleagues in New York City and Connecticut, is leading a clinical trial of convalescent plasma, a form of antibody-based therapy for the disease. [10] The treatment involves the administration of convalescent plasma, the liquid portion of blood containing antibodies to SARS-CoV-2, which is obtained from people who have recently recovered from COVID-19. [10] [11] [12] This type of treatment is being studied for its efficacy in patients who are exposed to SARS-CoV-2, as well as those suffering from COVID-19. [10] [13] Convalescent plasma therapy is a form of passive immunization that provides patients with antibodies to fight the disease. In the absence of a vaccine, passive immunization is a powerful way to provide antibodies and boost the immune system of people with SARS-CoV-2 [14] and may remain particularly important for immunocompromised people who may not be able to mount a strong vaccine response. The treatment was approved by the Food and Drug Administration on March 24, 2020. [15] and as of July 2020 numerous randomized controlled clinical trials of its efficacy in hospitalized patients and outpatients are ongoing. Pirofski has found the way in which recovered patients came forth to donate their plasma to treat others heartwarming and a celebration of their spirit and courage in wanting to help others and contribute to the advancement of evidence based science. [16]
Pirofski has been chief of the Division of Infectious Diseases and the Jacques and Selma Mitrani Chair in Biomedical Research at Albert Einstein College of Medicine and Montefiore Medical Center since 2006. [17] In an article describing her career as a physician scientist, she wrote “The greatest treasure my career has brought is the opportunity to support and encourage others in their effort to make inroads in the fields of infectious diseases, immunity, and microbial pathogenesis. Although my own accomplishments and the advances to which I have contributed are very satisfying, what makes my days worthwhile is the thought that my support and encouragement might help others make discoveries that may alleviate suffering and improve human health.” [18]
Dr. Pirofski is a Fellow of the Infectious Diseases Society of America [25] and the American College of Physicians. [2]
Antiserum is a blood serum containing monoclonal or polyclonal antibodies that is used to spread passive immunity to many diseases via blood donation (plasmapheresis). For example, convalescent serum, passive antibody transfusion from a previous human survivor, used to be the only known effective treatment for ebola infection with a high success rate of 7 out of 8 patients surviving.
Serology is the scientific study of serum and other body fluids. In practice, the term usually refers to the diagnostic identification of antibodies in the serum. Such antibodies are typically formed in response to an infection, against other foreign proteins, or to one's own proteins. In either case, the procedure is simple.
Stanley "Stan" Falkow was an American microbiologist and a professor of microbiology at Georgetown University, University of Washington, and Stanford University School of Medicine. Falkow is known as the father of the field of molecular microbial pathogenesis. He formulated molecular Koch's postulates, which have guided the study of the microbial determinants of infectious diseases since the late 1980s. Falkow spent over 50 years uncovering molecular mechanisms of how bacteria cause disease and how to disarm them. Falkow also was one of the first scientists to investigate antimicrobial resistance, and presented his research extensively to scientific, government, and lay audiences explaining the spread of resistance from one organism to another, now known as horizontal gene transfer, and the implications of this phenomenon on our ability to combat infections in the future.
Montefiore Medical Center is a premier academic medical center and the primary teaching hospital of the Albert Einstein College of Medicine in the Bronx, New York City. Its main campus, the Henry and Lucy Moses Division, is located in the Norwood section of the northern Bronx. It is named for Moses Montefiore and is one of the 50 largest employers in New York. In 2020, Montefiore was ranked No. 6 New York City metropolitan area hospitals by U.S. News & World Report. Adjacent to the main hospital is the Children's Hospital at Montefiore, which serves infants, children, teens, and young adults aged 0–21.
Passive immunity is the transfer of active humoral immunity of ready-made antibodies. Passive immunity can occur naturally, when maternal antibodies are transferred to the fetus through the placenta, and it can also be induced artificially, when high levels of antibodies specific to a pathogen or toxin are transferred to non-immune persons through blood products that contain antibodies, such as in immunoglobulin therapy or antiserum therapy. Passive immunization is used when there is a high risk of infection and insufficient time for the body to develop its own immune response, or to reduce the symptoms of ongoing or immunosuppressive diseases. Passive immunization can be provided when people cannot synthesize antibodies, and when they have been exposed to a disease that they do not have immunity against.
A neutralizing antibody (NAb) is an antibody that defends a cell from a pathogen or infectious particle by neutralizing any effect it has biologically. Neutralization renders the particle no longer infectious or pathogenic. Neutralizing antibodies are part of the humoral response of the adaptive immune system against viruses, intracellular bacteria and microbial toxin. By binding specifically to surface structures (antigen) on an infectious particle, neutralizing antibodies prevent the particle from interacting with its host cells it might infect and destroy.
In biology, a pathogen, in the oldest and broadest sense, is any organism or agent that can produce disease. A pathogen may also be referred to as an infectious agent, or simply a germ.

Convalescent plasma is the blood plasma collected from a survivor of an infectious disease. This plasma contains antibodies specific to a pathogen and can be used therapeutically by providing passive immunity when transfusing it to a newly infected patient with the same condition. Convalescent plasma can be transfused as it has been collected or become the source material for the hyperimmune serum which consists largely of IgG but also includes IgA and IgM. or as source material for anti-pathogen monoclonal antibodies, Collection is typically achieved by apheresis, but in low-to-middle income countries, the treatment can be administered as convalescent whole blood.

Although several medications have been approved in different countries as of April 2022, not all countries have these medications. Patients with mild to moderate symptoms who are in the risk groups can take nirmatrelvir/ritonavir or remdesivir, either of which reduces the risk of serious illness or hospitalization. In the US, the Biden Administration COVID-19 action plan includes the Test to Treat initiative, where people can go to a pharmacy, take a COVID test, and immediately receive free Paxlovid if they test positive.
