FAQs

Respiratory Syncytial Virus (RSV) is a highly contagious virus that can lead to respiratory infection in babies, including serious lung infections. However, most of the time RSV will cause a mild, cold-like illness. RSV spreads when droplets from a cough, sneeze, or infected surface get inside the eyes, nose, or mouth.

The typical RSV season usually occurs from fall through spring, but can vary by local area.

Most of the time RSV will cause a mild, cold-like illness. Initial symptoms of RSV can include:

  • congestion
  • runny nose
  • irritability
  • decreased appetite
  • fever

As the infection spreads to the lungs the symptoms can worsen and can also cause severe illness such as bronchiolitis or pneumonia. Symptoms can include:
  • short, shallow, and abnormally fast breathing
  • a wheezing cough
  • cnasal flaringoughing
  • poor feeding
  • unusual tiredness
  • developing a blue tint to their lips or fingernails
  • fever

Beyfortus® (nirsevimab-alip) 50 mg and 100 mg injection is a preventative antibody that gives babies the protection against RSV they lack. Beyfortus can help prevent serious lung infections, like pneumonia caused by RSV, in babies under 1 year of age born during or entering their first RSV season. Beyfortus may not protect all children.

The most common side effects of Beyfortus include rash and pain, swelling, or hardness at the site of your baby’s injection. In clinical trials, 1.2% of babies who received Beyfortus reported any side effects.

These are not all the possible side effects of Beyfortus. Call your healthcare provider if you have questions about side effects.
