Summary

This study checks how well the RSV vaccine (ABRYSVO) works when given to pregnant women to protect their babies from severe RSV illness. Researchers will look at health records of infants hospitalized with breathing problems in Australia. They want to see if vaccinated moms' babies are less likely to end up in the hospital with RSV.
