Call for Universal RSV Vaccination for Pregnant Women and Children Highlights New Research

A recent study supported by researchers from the University of Florida emphasizes the critical need for universal immunization against respiratory syncytial virus (RSV) among pregnant women and young children. The research, which analyzed hospital data from Canada, underscores the significant health and economic burden caused by RSV, a leading cause of lung infections and pneumonia in pediatric populations.

The study, published in The Lancet Regional Health Americas, reveals that nearly 45% of RSV-related hospitalizations in children under six months occur within this age group, accounting for substantial healthcare costs—approximately $23 million USD annually in Canada alone. Infants hospitalized due to RSV often experience severe symptoms such as wheezing, difficulty in breathing, and barking coughs. While most children recover at home, 1-2% require hospitalization, and those born prematurely or with pre-existing health conditions face higher risks.

The researchers advocate for integrating RSV monoclonal antibodies and maternal RSV vaccines into immunization programs globally. Maternal vaccines administered during late pregnancy can protect infants for up to five months after birth, whereas neonatal vaccines given at birth can provide protection for up to six months. This approach could drastically reduce the rate of severe RSV cases and hospitalizations.

Given that 90% of children worldwide are affected by RSV before their second birthday, implementing these preventive strategies holds promise to alleviate the global disease burden. This is particularly urgent given the extensive hospitalizations and healthcare costs associated with pediatric RSV infections.

Vadlamudi, a co-author of the study, stresses the importance of swiftly adopting vaccination policies. "Adding RSV monoclonal antibodies or maternal vaccines to immunization schedules can provide vital protection for the most vulnerable infants, reducing both health risks and economic impacts," she said.

The study calls on policymakers to prioritize RSV vaccination efforts as part of broader child and maternal health strategies to prevent severe illness and hospitalization in early childhood.
