Now that we’re well into RSV season (October 1 – March 31), the pediatricians might be offering your tot the RSV immunization, Nirsevimab. Notice I didn’t say vaccine. Let’s talk about it.
What is RSV?
According to the Centers for Disease Control (CDC), RSV stands for Respiratory Syncytial Virus. It starts off similar to a common cold but infants less than 19 months and the elderly (over 60 years old) population are more likely to have severe symptoms that need to be managed in the hospital setting. Severe symptoms include difficulty breathing, low oxygen levels, and dehydration. Some infants may even die.
What is Nirsevimab and how does it protect my baby?
It’s an injectable monoclonal antibody that provides passive immunity. Meaning it doesn’t illicit a response from our immune system so it will not last as long as a vaccine. But good news is, the antibodies last in your system for the season and provide enough protection so your little one won’t end up in the hospital. According to the latest research, the immunization is 80-90% effective is preventing hospitalization.
In contrast, a vaccine, may introduce a live or weakened version of a virus to illicit a response from your immune system also known as creating antibodies against the targeted virus.
Who should avoid it?
Anyone who had an allergic reaction to Nirsevimab or any of its components. Below is the link for the fact sheet.
