Author name: Gertrud U. Rey

Gertrud Rey (who also goes by Trudy Rey) is a trained virologist who resides in Atlanta, Georgia. She has a PhD in molecular genetics and biochemistry from Georgia State University, where her studies involved the analysis of various aspects of the genetics of West Nile virus and simian hemorrhagic fever virus. After finishing the PhD program in 2007, she completed a post-doctoral fellowship at the Centers for Disease Control and Prevention, where she continued to study virology in the context of respiratory syncytial virus, with a more pronounced focus on immunology. During that time, she was also a lecturer at Georgia State University, where she designed an undergraduate biology course and supervised teaching assistants at the university’s biology laboratory. In 2012, she decided to retire from bench science and lecturing to pursue a career in patent law. She is now registered as a patent agent at the U.S. Patent and Trademark Office, and works for a major law firm. Her day to day responsibilities include preparing and prosecuting U.S. and international patent applications in the field of molecular and cell biology, virology, biochemistry, genetic engineering, tissue engineering, transgenic biology, stem cell research, immunology, drug delivery, phage therapeutics, and medical devices. However, Trudy still spends much of her free time communicating science, both for virology blog, and for her very own YouTube channel, where she hosts a show about viruses called “Catch This.” You can also find her on X and Bluesky, under the handle “Dr. T.” Trudy was also a guest on TWiV 179 and 424.

A Case of Misdirected Immunity

1 Comment / Basic virology, Gertrud Rey, Information / By

by Gertrud U. Rey Vaccination with the AstraZeneca and Johnson & Johnson adenovirus‑based COVID-19 vaccines has been linked to a very rare but serious adverse event known as vaccine‑induced immune thrombotic thrombocytopenia (VITT). Based on this small but significant risk, the U.S. Food and Drug Administration revoked the emergency use authorization for the Johnson & …

A Viral Battle in the Rice Field

1 Comment / Basic virology, Commentary, Gertrud Rey, Information / By

by Gertrud U. Rey Across Asia and beyond, rice crops are frequently attacked by planthoppers and leafhoppers – insects that damage plants during feeding and transmit viruses that can wipe out entire harvests. The chemical insecticides typically used by rice farmers can pose environmental and health risks, and they often also become less effective over …

Why We Vaccinate Newborns Against Hepatitis B

1 Comment / Basic virology, Commentary, Events, Gertrud Rey, Information / By

by Gertrud U. Rey On December 16, 2025, the Centers for Disease Control and Prevention (CDC) adopted new recommendations from the Advisory Committee on Immunization Practices (ACIP) that end universal hepatitis B vaccination at birth. Under this policy, parents may defer vaccination if the mother tests negative for hepatitis B virus (HBV). This decision disregards …

A Viral Risk Factor for Lupus

Basic virology, Commentary, Gertrud Rey, Information / By

by Gertrud U. Rey Epstein-Barr virus (EBV) is a common human herpesvirus that typically spreads through saliva and is known for causing infectious mononucleosis (i.e., “mono”). There is an established causal link between infection with EBV and the development of multiple sclerosis. Emerging evidence now suggests that EBV may also play a significant role in …

Vaccine Modalities – Part 2

Basic virology, Commentary, Gertrud Rey, Information / By

by Gertrud U. Rey Last month’s post provided an overview of various traditional vaccine technologies. The current post highlights more recent advances in the field. Genetic vaccines introduce nucleic acids (DNA and/or RNA) into a recipient’s cells. Once inside the cells, these genetic instructions are used by the cell’s machinery to produce a specific protein. …
