What is severe RSV disease?

Severe RSV disease is the number one reason babies under 12 months old have to be admitted to hospitals in the US.

Respiratory syncytial virus (sin-SISH-shul VI-rus), or RSV, is a common, seasonal, and easily spread virus. In fact, nearly all children will get their first RSV infection by age 2.

Some common symptoms of RSV disease include:

  • Runny nose
  • Cough
  • Sneezing
  • A fever (especially if it is greater than 100.4°F in infants under 3 months of age)

Some signs and symptoms of severe RSV disease include:

  • Coughing or wheezing that does not stop
  • Fast or troubled breathing
  • A bluish color around the mouth or fingernails
  • Spread-out nostrils and/or a caved-in chest when trying to breathe
  • Gasping for breath

It's never too early to ask your baby's doctor if your baby is at high risk for severe RSV disease.

Your premature child can be put at risk of catching RSV by things like:

Take simple steps to help protect your baby from RSV.

  • Wash your hands before touching your child. Make sure others wash up, too
  • Clean toys, crib rails, and any other surfaces your baby might touch
  • Try to keep your baby away from crowds. Avoid anyone with a cold or fever
  • Don't let anyone smoke near your baby. Tobacco smoke can increase the risk of severe RSV disease

Important Safety Information

What is Synagis® (palivizumab)?

Synagis is a prescription medication that is used to help prevent a serious lung disease caused by respiratory syncytial virus (RSV) in children at high risk for severe lung disease from RSV.

Who should not receive Synagis?

Children should not receive Synagis if they have ever had a severe allergic reaction to it. Signs and symptoms of a severe allergic reaction could include itchy rash; swelling of the face; difficulty swallowing; difficulty breathing; bluish color of the skin; muscle weakness or floppiness; a drop in blood pressure; and/or unresponsiveness. If your child has any of these signs or symptoms of a severe allergic reaction after getting Synagis, be sure to tell your child’s healthcare provider or get medical help right away.

How is Synagis given?

Synagis is given as a shot, usually in the thigh muscle, each month during the RSV season. Your child should receive their first Synagis shot before the RSV season starts, to help protect them before RSV becomes active. When RSV is most active, your child will need to receive Synagis shots every 28-30 days to help protect them from severe RSV disease for about a month. Your child should continue to receive monthly shots of Synagis until the end of RSV season. Your child may still get severe RSV disease after receiving Synagis. If your child has an RSV infection, they should continue to get their monthly shots throughout the RSV season to help prevent severe disease from new RSV infections.

The effectiveness of Synagis shots given less than monthly throughout the RSV season has not been established.

What are the side effects of Synagis?

Possible, serious side effects include severe allergic reaction, which may occur after any dose of Synagis. Such reactions may be life-threatening or cause death. Unusual bruising and/or groups of tiny red spots on the skin have also been reported.

Common side effects of Synagis include fever and rash. Other possible side effects include skin reactions around the area where the shot was given (like redness, swelling, warmth, or discomfort).
