About this active substance

The respiratory syncytial virus (RSV) vaccine is used to prevent severe infections caused by this virus, which primarily affects infants, young children, and the elderly. RSV is a major cause of bronchiolitis and pneumonia, accounting for a significant number of hospitalizations and deaths worldwide.

The vaccine is administered intramuscularly, usually in multiple doses, depending on the recommended vaccination schedule. It is particularly indicated for high-risk infants, such as those born prematurely or with chronic lung conditions, as well as older adults with comorbidities.

Common side effects include pain at the injection site, mild fever, fatigue, and irritability. In rare cases, severe allergic reactions may occur.

The RSV vaccine is an essential preventive measure for reducing the incidence and severity of respiratory infections, helping to protect vulnerable populations and alleviate the burden on healthcare systems.
