Today, more children and older adults are getting severe RSV infections. In the winter of late 2020 into early 2021, there were almost no cases of RSV.
Some children and babies have little natural protection. That’s because their immunity has lessened, or they weren’t exposed to respiratory viruses before the pandemic.
For older adults, the population of people over 60 is larger now than it has ever been before, and more people are immunocompromised than before the pandemic.1
