Understanding Side Effects of RSV Shot in Infants & Adults

The Respiratory Syncytial Virus (RSV) is a highly contagious virus that affects people of all ages, but it is most severe in young children and older adults. Recently, a new RSV vaccine has been approved for use in infants and adults, offering protection against this virus. However, like all vaccines, the RSV shot can cause side effects. Understanding these side effects is crucial for parents and healthcare providers to make informed decisions about vaccination.

RSV is a common virus that affects the respiratory system, causing mild to severe symptoms. In infants, RSV can lead to bronchiolitis and pneumonia, while in adults, it can cause respiratory illness, particularly in those with weakened immune systems or underlying health conditions. The new RSV vaccine aims to provide protection against severe RSV disease, reducing the risk of hospitalization and death.
