Study Notes
- RSV (Respiratory Syncytial Virus) infection can lead to severe complications and poor outcomes in adults, particularly those with weakened immune systems or certain comorbidities.
- Risk factors for severe RSV-associated disease in adults include older age, comorbidities such as asthma, chronic obstructive pulmonary disease (COPD), congestive heart failure (CHF), coronary artery disease (CAD), chronic kidney disease (CKD), and weak immune status, especially for those aged ≥60 years.
- Older adults are particularly susceptible to severe RSV-associated disease due to age-related decline in immunity, aging of the lung, and high rates of comorbidities.
- RSV infection in healthy adults typically results in mild, cold-like symptoms. However, in older adults and those with comorbidities, it can lead to lower respiratory tract infections, hospitalization, exacerbation of certain comorbidities, and death.
- Respiratory viral infections, including RSV, are a major factor in the worsening of COPD and asthma. They can lead to longer hospitalization, accelerated lung function decline, greater hypoxemia, and greater airway inflammation.
- The RENOIR study showed that the RSVPreF vaccine had vaccine efficacy against RSV-associated illness during the first RSV season, with 66.7% RSV-LRTI and 85.7% RSV-LRTI ≥3 signs/symptoms in the RSVPreF group compared to 14.3% and 0% in the placebo group, respectively.
- Solicited adverse events (AEs) reported within 7 days of vaccination included pain (11%) and fatigue (16%) in the RSVPreF group compared to 10% and 14% in the placebo group, respectively. The median duration of these AEs was 1-2 days.
