Older adults may have a reduced ability to mount an effective immune response1,2

THIS LEAVES THEM MORE SUSCEPTIBLE TO ACUTE VIRAL INFECTIONS.2

RSV infection in adults usually presents as mild disease with cold-like symptoms, but it can progress to more severe disease involving the lower respiratory tract, such as pneumonia.1 RSV and influenza have overlapping seasonality and similar presenting symptoms and may be difficult to distinguish based on clinical presentation alone.10
