What is RSV?

RSV is a highly contagious virus that can lead to respiratory illness in babies, including lung infections. Without a fully developed immune system, all babies under 1 year – even healthy ones – are at serious risk of getting RSV.

FAQs

Beyfortus is an antibody that contains nirsevimab-alip which is used to help prevent RSV disease for 5 months. It is not known if Beyfortus is safe and effective in children older than 24 months of age.

RSV symptoms can include a runny nose, sneezing, congestion, coughing, fever, decreased appetite, and wheezing. In babies with RSV, the only symptoms may be irritability, decreased activity, and breathing difficulties, according to the CDC.   For more information on RSV symptoms in babies, talk to your doctor or pediatrician.

RSV can often mimic a cold or the flu. But as the infection becomes more severe, so do the symptoms. For more information on the differences between RSV and the flu, talk to your doctor or pediatrician.

Since most RSV cases are mild, testing is usually not required to diagnose the infection. However, depending on your baby’s medical history and the time of year, their doctor may do a nose swab or blood test to look for viruses and check white blood cell counts. In more severe RSV cases where hospitalization is required, your doctor may do a chest X-ray or CT scan to check for lung complications.   For more information on how RSV is diagnosed, talk to your doctor or pediatrician.

IMPORTANT SAFETY INFORMATION

Your child should not take Beyfortus if your child has a history of serious allergic reactions to nirsevimab-alip or any of the ingredients in Beyfortus.

Before your child receives Beyfortus, tell your healthcare provider about all of your child’s medical conditions, including if your child:

has ever had a reaction to Beyfortus.
has bleeding or bruising problems. If your child has a problem with bleeding or bruises easily, an injection could cause a problem.

Tell your healthcare provider about all the medicines your child takes, including prescription and over-the-counter medicines, vitamins, and herbal supplements. Your infant should not receive a medicine called palivizumab if they have already received Beyfortus in the same RSV season.

Serious allergic reactions have happened with other medicines like Beyfortus. Get medical help right away if your child has any of the following signs or symptoms of a serious allergic reaction:

swelling of the face, mouth, or tongue
difficulty swallowing or breathing
unresponsiveness
bluish color of skin, lips, or under fingernails
muscle weakness
severe rash, hives, or itching

The most common side effects of Beyfortus include rash and pain, swelling, or hardness at the site of your child’s injection. These are not all the possible side effects of Beyfortus. Call your healthcare provider if you have questions about side effects.
