Few subjects are timelier in pulmonology right now than respiratory syncytial virus (RSV). As the US begins the latest fall-winter season of high RSV transmission, it does so armed with its first available vaccine: Arexvy, for the prevention of lower respiratory tract disease caused by RSV, in adults ≥60 years old.1

What’s more, the introduction of a new vaccine adds a dynamic to what is anticipated to become a recurring health decision for adults in each fall: among the available RSV, influenza and COVID-19 vaccine doses available, who should take what—and when?

In the September 2023 episode of Lungcast, a pulmonologist and infectious disease specialist pair up to set everything straight in RSV preparedness.

Lungcast host Albert Rizzo, MD, chief medical officer of the American Lung Association, and member of the HCPLive Editorial Advisory Board, speaks with Barbara S. Taylor, MD, MS, associate professor of infectious diseases and assistant dean for the MD/MPH program at UT Health San Antonio, for a review on what’s new and what’s emerging in modern RSV epidemiology and prevention.

Throughout the episode, Rizzo and Taylor discuss the new RSV season; available and investigative vaccines; in vitro immunization; the risk of a “triple-epidemic” between RSV, flu and COVID-19; monoclonal antibodies and other therapies for RSV; and the future prospects for overall respiratory virus prevention and vaccine development.

Lungcast is a monthly respiratory health podcast series from the ALA produced by HCPLive.
