Lower respiratory infection, such as pneumonia Which age group is most likely to experience severe RSV cases? Infants and young children What adult population is at higher risk for severe RSV? Adults with chronic medical conditions How does age affect RSV severity in older adults? Older adults, especially 65 years and older, are at increased risk Why are premature infants at higher risk for severe RSV? They have underdeveloped lungs/immune systems, making them more vulnerable Which infants are particularly at risk for severe RSV? Infants 6 months and younger What conditions increase RSV risk in children under 2 years? Chronic lung disease or congenital heart disease How does immune status affect RSV severity in children? Children with weakened immune systems are more susceptible What chronic conditions increase RSV risk in adults? Chronic heart or lung disease How does immune suppression affect RSV risk in adults? Adults with weakened immune systems are more likely to develop severe illness What is Nirsevimab-alip (Beyfortus)? A long-acting monoclonal antibody used for passive immunization against RSV How is Beyfortus administered? Intramuscular injection How long does passive immunization from Beyfortus last? Up to 150 days What dose of Beyfortus should infants under 8 months receive during their first RSV season? One dose - 50 mg for infants <5 kg, 100 mg for infants >/= 5 kg Which children qualify for RSV immunization during their second season? 8-19 months who are at increased risk of severe RSV disease What is the recommended dose for high-risk children entering their second RSV season? One dose of 200 mg What is Clesrovimab (Enflonsia)? A long-acting monoclonal antibody used for passive immunization against RSV Who is Clesrovimab indicated for?

Approximately 150 days What is the shared recommendation for Clesrovimab and Nirsevimab? Both are recommended for infants under 8 months of age born during or entering their first RSV season When is RSV immunization typically administered in the U.S.? Between October and March Under what conditions should infants receive Clesrovimab or Nirsevimab? If the mother did not receive RSV vaccine during pregnancy If the mother's RSV vaccination status is unknown If the infant was born less than 14 days after maternal RSV vaccination What RSV product is recommended for infants and young children? Infant RSV antibody only What RSV vaccine is recommended during pregnancy? Abrysvo (Pfizer) only What RSV vaccines are approved for older adults? Abrysvo (Pfizer), Arexvy (GSK), and mResvia (Moderna) What high-risk groups were shown to benefit from RSV vaccination? Adults aged 75 years or older Adults with immunocompromising conditions Adults with underlying cardiopulmonary disease Who is universally recommended to receive the RSV vaccine? All adults 75 years and older should receive a single dose of the RSV vaccine What is the recommendation for adults aged 50-74? Adults 50-74 years old who are at increased risk of severe RSV disease should receive a single dose of the RSV vaccine Is RSV vaccination a recurring or one-time dose? Single lifetime dose Should adults 50-74 without risk factors receive the RSV vaccine? No When should RSV vaccination ideally occur? Before the onset of increased RSV activity—late summer or early fall is optimal Can older adults receive RSV vaccination year-round? Yes, using shared clinical decision-making, older adults may be vaccinated year-round Is coadministration of RSV vaccine with other adult vaccines allowed? Yes Which vaccines can be coadministered with RSV vaccine? Flu, COVID-19, pneumococcal, Td/Tdap, and recombinant zoster vaccine What do Shingrix and Arexvy have in common?
