She founded Stanford's pediatric HIV Clinic and now serves as Stanford University School of Medicine's Senior Associate Dean of Faculty Development and Diversity.

Contents

Early life

Raised in Los Angeles, Maldonado is the daughter of Mexican immigrants and was the first in her family to attend college. [1] Maldonado received her bachelor's degree from University of California, Los Angeles. [2] She then attended Stanford University School of Medicine, where she received her Doctor of Medicine degree in 1981. She then performed her residency in pediatrics at Johns Hopkins Hospital, where she remained for her fellowship in pediatric infectious diseases. [3]

Career

Following her residency she joined the Centers for Disease Control and Prevention as an Epidemic Intelligence Service (EIS) Officer in the mid-1980s at the beginning of the HIV/AIDS epidemic in the United States. [3] [4] There, she became interested in how to prevent the spread of HIV infection from mothers to their babies, particularly in developing countries. In 1988, she became a professor of pediatrics at Stanford University, where she started the pediatric HIV Clinic. [3]

Leadership and service

Maldonado has contributed her expertise to governmental policy, serving on the National Vaccine Advisory Committee through the United States Department of Health and Human Services and as a member of Governor Gavin Newsom's California Initiative to Advance Precision Medicine Advisory Council. [5] She is the Chair of the committee on infectious diseases at the American Academy of Pediatrics and serves as a Senior Fellow at the Stanford Center for Innovation in Global Health. [6] She is also an advocate for diversity, equity, and inclusion, serving as Stanford's Associate Dean of Faculty Development and Diversity since May 2014, succeeding Hannah Valantine. [7]

Research

Her research focuses on the epidemiology and prevention of infectious diseases, such as rotavirus, measles, mumps, rubella, polio, and pediatric HIV infection. She has also worked on developing and evaluating programs to prevent gender-based violence, working on interventions in Kenya. Her group partnered with the non-profit "Ujamaa-Africa/No Means No Worldwide" to develop and implement a 12-hour empowerment program to teach girls verbal and physical techniques to prevent sexual harassment and assault. [8] [9] They found the intervention was successful in both curbing the incidence of sexual assault and increasing the likelihood that girls would disclose assault.

HIV research

One of Maldonado's research interests is preventing perinatal HIV transmission, which includes preventing transmission through breastfeeding and maximizing prevention strategies in developing countries. She and her colleagues found that treating infants with the anti-retroviral drug nevirapine for their first six months of life reduces HIV transmission through breastfeeding. [10] [11]

Vaccine research

Maldonado's research program also focuses on the development and implementation of vaccines. Her group has received funding from the Bill & Melinda Gates Foundation to understand the factors that underlie the poor immunogenicity of the oral polio vaccine among children in three communities in Orizaba, Veracruz, Mexico with the goal of understanding how to improve immunogenicity. She also studies the circulation and epidemiology of vaccine-derived polioviruses, which originate from the live oral vaccine used against polio. [12] She notes the live vaccine is still in use in developing countries, despite associated risks, because it is much cheaper and because manufacturers are still working to ramp up production of the inactivated vaccine, which is five times more expensive (as of 2018). [13]

She has also analyzed the efficacy of mandatory vaccination policies, which have been implemented in some European countries. [14] She also found that California's elimination of non-medical vaccine exemptions for students entering school in 2016 also led to an increase in vaccine coverage. [15] [16] While mandates are effective in increasing immunization, Maldonado and her colleagues have also advocated for interventions to combat misinformation and address vaccine hesitancy. [17]

COVID-19 response

Maldonado and her team have been involved in many of the studies at Stanford University seeking to understand the biology and epidemiology of SARS-CoV-2. [18] She has worked on a study of the accuracy of three different self-administered nasal swab techniques, which would allow individuals to test themselves for infection without the need to come to the hospital. [19] [2] In the meantime, she has spoken of the importance of drive-through COVID-19 testing, which Stanford implemented to minimize the risk of spreading the disease at hospitals. [20] She also launched a study to understand how COVID-19 is transmitted within a household. [21] Adults who come into the hospital for COVID-19 were asked to perform at-home nose swab tests, along with all members of their household, as well as keep a symptom log to understand when infection is spread and whether that spread occurs before or after symptoms have disappeared. [21] Her team also worked to develop and implement an antibody test to determine if someone had contracted COVID-19; the test was approved by the Food and Drug Administration in early April 2020. [22]

The management of HIV/AIDS normally includes the use of multiple antiretroviral drugs as a strategy to control HIV infection. There are several classes of antiretroviral agents that act on different stages of the HIV life-cycle. The use of multiple drugs that act on different viral targets is known as highly active antiretroviral therapy (HAART). HAART decreases the patient's total burden of HIV, maintains function of the immune system, and prevents opportunistic infections that often lead to death. HAART also prevents the transmission of HIV between serodiscordant same-sex and opposite-sex partners so long as the HIV-positive partner maintains an undetectable viral load.

<span class="mw-page-title-main">Infectious diseases (medical specialty)</span> Medical specialty dealing with the diagnosis, control and treatment of infections

Infectious diseases (ID), also known as infectiology, is a medical specialty dealing with the diagnosis and treatment of infections. An infectious diseases specialist's practice consists of managing nosocomial (healthcare-acquired) infections or community-acquired infections. An ID specialist investigates and determines the cause of a disease. Once the cause is known, an ID specialist can then run various tests to determine the best drug to treat the disease. While infectious diseases have always been around, the infectious disease specialty did not exist until the late 1900s after scientists and physicians in the 19th century paved the way with research on the sources of infectious disease and the development of vaccines.

HIV in pregnancy is the presence of an HIV/AIDS infection in a woman while she is pregnant. There is a risk of HIV transmission from mother to child in three primary situations: pregnancy, childbirth, and while breastfeeding. This topic is important because the risk of viral transmission can be significantly reduced with appropriate medical intervention, and without treatment HIV/AIDS can cause significant illness and death in both the mother and child. This is exemplified by data from The Centers for Disease Control (CDC): In the United States and Puerto Rico between the years of 2014–2017, where prenatal care is generally accessible, there were 10,257 infants in the United States and Puerto Rico who were exposed to a maternal HIV infection in utero who did not become infected and 244 exposed infants who did become infected.

Vaccine shedding is a form of viral shedding which can occasionally occur following a viral infection caused by an attenuated vaccine. Illness in others resulting from transmission through this type of viral shedding is rare. The idea of shedding is a popular anti-vaccination myth. However, most vaccines are not attenuated vaccines, and therefore cannot cause vaccine-induced viral shedding.
