Understanding RSV and the Importance of Vaccination


Respiratory Syncytial Virus (RSV) is a common respiratory virus that affects people of all ages, but it is particularly dangerous for infants, older adults, and those with compromised immune systems. RSV is the leading cause of bronchiolitis in children under one year of age and can lead to severe respiratory illness requiring hospitalization.

The Threat of RSV

RSV spreads through respiratory droplets when an infected person coughs or sneezes. The virus can survive on surfaces, making it easy to spread in environments like schools and daycare centers. It can spread from a simple kiss on the cheek or by snuggling a favorite toy. While most people recover from RSV with mild, cold-like symptoms, it can cause severe illness in vulnerable populations. According to the CDC, RSV is responsible for thousands of hospitalizations and several hundred deaths annually in the United States.

RSV Symptoms

RSV, the flu, and COVID-19 are all respiratory illnesses that can have similar symptoms like fever, cough, and shortness of breath. These illnesses are caused by different viruses and are difficult to differentiate based on symptoms. If your child has symptoms, please call Goldsboro Pediatrics for advice and to see if an appointment for further evaluation is needed.

Most of the time RSV is like a mild cold with:

  • Congestion
  • Runny nose
  • Mild irritability
  • Decreased appetite
  • Fever

It’s time to call a doctor when you see:

  • Short, shallow or fast breathing
  • Wheezing cough
  • Nasal flaring
  • Not eating
  • Tiredness
  • Blue tint to lips and or fingernails
  • Higher fever

Introducing Beyfortus: A Game-Changer in RSV Prevention

Beyfortus (nirsevimab) is a monoclonal antibody designed to prevent RSV in infants and young children. Unlike traditional vaccines that stimulate the immune system to produce antibodies, Beyfortus provides immediate, passive immunity by supplying antibodies that neutralize the RSV virus. This approach is particularly beneficial for infants who are too young to receive vaccines or whose immune systems are not yet fully developed.

Who Should Get Beyfortus?

Beyfortus is recommended for:

  • Infants: Especially those born prematurely, with chronic lung disease, congenital heart disease or other conditions that make them more susceptible to severe RSV.
  • Young children: Up to 2 years old who are at high risk for severe RSV disease.
  • Pregnant women: Vaccination in their third trimester
  • Adults age 60-74 at increased risk of severe RSV
  • Adults age 75+

Benefits of RSV Vaccination in Pregnancy

One of the most effective ways to protect newborns from RSV is through maternal vaccination during pregnancy. Recent advancements have led to the development of RSV vaccines specifically designed for pregnant women. When administered during the third trimester, between 28 and 36 weeks of gestation, the vaccine helps transfer protective antibodies from the mother to the unborn child, providing the infant with immunity against RSV during the critical first months of life during peak RSV season. Studies have shown that maternal RSV vaccination can significantly reduce the number of RSV-related hospitalizations in infants, easing the burden on healthcare systems and providing peace of mind for parents.

Dosing Information

Beyfortus is administered as a single intramuscular injection, typically given before the RSV season begins. This ensures that the infant or child has sufficient antibodies to protect them throughout the peak RSV season which usually lasts from fall to spring. Goldsboro Pediatrics will start administering Beyfortus on October 1.

Risks and Considerations

As with any medical treatment, Beyfortus carries some risks. Common side effects include:

  • Mild reactions at the injection site, such as redness, swelling, or pain
  • Fever
  • Rash

Serious allergic reactions are rare but possible. Parents and caregivers should monitor children for any signs of an allergic reaction, such as difficulty breathing, swelling of the face, mouth, tongue or throat, bluish color skin, lips or fingernails, or severe rash. Seek immediate medical attention if any of these conditions occur.

The Broader Importance of RSV Vaccination

Preventing RSV through vaccination or monoclonal antibodies like Beyfortus is crucial for reducing the burden of this virus on families and the healthcare system. Vaccination not only protects the individual but also contributes to community immunity, helping to shield those who are too young or too vulnerable to be vaccinated.

RSV is a significant public health threat, especially for young children and infants. Vaccination and preventive measures like Beyfortus offer a powerful defense against this virus, helping to reduce the incidence of severe disease, hospitalizations, and deaths. Parents should consult with their provider at Goldsboro Pediatrics to determine the best course of action for protecting their children against RSV, particularly as the RSV season approaches.
