Introducing the New RSV Shot for Babies

RSV, short for respiratory syncytial virus, is a common virus that typically only causes cold symptoms in most people. However, for infants and young children with certain health conditions, RSV can pose serious risks. Luckily, a revolutionary immune-boosting therapy has emerged as a potential solution.

What kind of complications can RSV cause?

RSV is the primary cause of bronchiolitis and pneumonia in children under one year old. Particularly for children with heart or lung diseases, it can lead to life-threatening breathing problems.

What treatment options are available for RSV?

Currently, there are no effective medications for treating RSV. However, a preventive medication called palivizumab (Synagis) can be administered monthly during the RSV season to high-risk infants. It's worth noting that while RSV can occur year-round, many cases are reported between late fall and early spring. Unfortunately, strict criteria set by insurance companies and the need for monthly doses have limited its accessibility.

How can the new RSV shot make a difference?

This year, a breakthrough called nirsevimab (Beyfortus) has emerged, which could be a game-changer. Like palivizumab, it is an antibody treatment, but unlike its counterpart, nirsevimab is available for all babies under eight months old, not just those considered high-risk. Here's what you need to know:

1. It's not a vaccine: Unlike vaccines that stimulate the body to produce protective antibodies, this shot directly provides the antibodies.

2. It can prevent or reduce the severity of an RSV infection by leveraging these antibodies.

3. Although the shot's effectiveness diminishes over time since the body isn't producing its own antibodies, a single shot can last five months. Administering it at the beginning of RSV season effectively protects your baby for the entire season.

Who is eligible for the new RSV shot?

For all babies under eight months old, it is recommended to receive one dose of nirsevimab as close to the start of RSV season as possible. Newborns can receive it before leaving the birth hospital, and it can be administered alongside routine vaccinations.

Additionally, children aged 8 to 19 months with certain conditions that put them at high risk of severe illness from RSV should also receive the new shot. These conditions include prematurity, chronic lung disease, congenital heart disease, weakened immune system, cystic fibrosis, neuromuscular disorders, and other disorders affecting swallowing and mucus clearance.

Notably, infants and toddlers who receive nirsevimab do not require monthly shots of palivizumab.

As this is a recent development, there may be challenges in ensuring accessibility for all eligible infants and toddlers. We recommend discussing eligibility with your doctor for this season.
