Learn more about the risk of RSV infection

RSV is a common and contagious virus that typically produces mild, cold-like symptoms in adults.1,2 However, older adults, including those with certain comorbidities*, are at risk of severe RSV infection.1-3

* Chronic heart or lung disease, or adults with weakened immune systems.

RSV fast facts

  • RSV-A and RSV-B subtypes co-circulate in Canada.4
  • RSV is very contagious. RSV virus has a basic reproduction number (R0) of 3.0.5,6
  • People can get repeat RSV infections, and individuals of any age can be infected.7
  • RSV infection can happen at any time of the year.8 It follows a seasonal pattern, and in Canada, a wave of increased activity usually occurs from fall to mid-to-late spring.1

Severe outcomes of RSV can include:1,3

AREXVY is not indicated for the treatment of RSV or its complications, such as hospitalizations.

Age-related decline in immunity describes a progressive decline in immune function that makes older adults more susceptible to numerous infections, including RSV.9

What is the impact of RSV in older adults?

Each year in the United States, approximately 177,000 older adults are hospitalized, and an estimated 14,000 die due to RSV.10

The mortality rate in patients ≥65 years hospitalized with RSV has been shown to be 1 in 9 patients.11*
