Understanding the RSV Virus and Its Impact on Infants
The respiratory syncytial virus, commonly known as RSV, is a widespread virus that primarily affects the lungs and airways. It is highly contagious, often spreading through close contact with an infected person or by touching contaminated surfaces. Due to its nature, RSV is a leading cause of bronchiolitis, which is the inflammation of the small airways in the lungs, and pneumonia, particularly in young children. These conditions can be pretty serious, especially in vulnerable populations.
Impact of RSV on Newborns and Infants
While RSV typically causes mild, cold-like symptoms in adults, it can have a much more severe impact on infants, particularly those who were born prematurely or have underlying health conditions. In these young ones, RSV can lead to significant health issues such as difficulty breathing, wheezing, persistent coughing, and challenges with feeding. In more severe cases, hospitalisation might become necessary to manage the symptoms effectively and ensure the infant receives the care they need.
The New Vaccine Programme for Pregnant Mothers in the UK
In 2024, the UK introduced a new vaccination programme aimed at protecting infants from severe RSV illness by vaccinating pregnant mothers. The vaccine, known as Abrysvo, is now offered to all pregnant individuals. Administering the vaccine between 28 and 36 weeks of pregnancy has proven to be the most effective way to protect babies from severe RSV-related illnesses. This initiative is a significant step forward in safeguarding the health of newborns.
Eligibility for Babies Missing the Maternal Vaccination Programme
Although maternal vaccination during pregnancy offers the best protection, there are specific situations where babies themselves may be eligible for direct immunisation. For instance, infants born prematurely, particularly those born before 29 weeks, may qualify for a monoclonal antibody injection such as nirsevimab or palivizumab. These medications provide passive immunity, helping to shield babies from severe RSV infections. Additionally, babies with certain medical conditions, like congenital heart disease or chronic lung disease, may also be eligible for these protective treatments.
Recognising RSV Infection in Infants and When to Seek Help
Parents must be aware of the common signs of RSV infection in infants. These symptoms include a runny nose, persistent cough, wheezing, difficulty breathing, poor feeding, and fever. If you notice that your baby is struggling to breathe, not feeding well, or appears unusually lethargic, it is essential to seek medical attention immediately. Early intervention can make a significant difference in the outcome for your child.
Additional Tips for Protecting Your Baby from RSV
There are several proactive steps you can take to protect your baby from RSV. Firstly, practising good hygiene is essential. Make sure to wash your hands frequently, especially after touching your face or surfaces in public areas. Furthermore, it is advisable to avoid close contact with individuals who are sick. Additionally, regularly clean and disinfect surfaces that are touched frequently. During RSV season, which typically occurs in the fall and winter, consider limiting your infant’s exposure to large crowds.
