The world remembers March 2020 as a time of escalating fear and uncertainty. For Dr. Sydney Ramirez,it was a pivotal moment that dramatically altered her career trajectory and propelled her to the forefront of COVID-19 research. Her story isn’t just about responding to a crisis; it’s about recognizing a critical, frequently enough overlooked, battleground in the fight against respiratory viruses: the upper airway.
Ramirez, a physician and immunologist, was poised to begin a postdoctoral fellowship at the La Jolla Institute for Immunology (LJI) under the guidance of renowned scientist Shane Crotty. Her focus was initially on the shingles vaccine and understanding how the immune system responds to vaccination. But when COVID-19 was declared a national emergency, and LJI braced for shutdown, everything changed.
Crotty, already anticipating the pandemic’s impact, recognized Ramirez’s unique expertise. Her Ph.D. research centered on coronavirus virology – a skillset suddenly in incredibly high demand. The urgent questions were overwhelming: Would people develop immunity to SARS-CoV-2? Who would be most vulnerable? And, crucially, could a vaccine even be developed?
Within 48 hours, Ramirez pivoted, joining Crotty’s lab and diving headfirst into the unknown. Weeks later, she would co-author a landmark paper offering crucial early insights into SARS-CoV-2 immunity.
Today, over five years later, Dr. Ramirez is a rising star, recognized as a STAT Wunderkind. She balances her roles as an instructor at LJI and an infectious disease physician at UC San diego, continuing her vital research on respiratory viruses. Her current work is focused on a surprisingly neglected area: the upper airway – the nose and throat – the first point of contact for these viruses before they reach the lungs.
Why the Upper Airway Matters
For decades, research has largely concentrated on the immune response within the lungs when battling respiratory infections. Ramirez
