Summary

This study tested an injection called TNM001 in over 2,200 babies under 1 year old to see if it could prevent serious lung infections caused by RSV. The goal was to reduce the number of babies who get sick enough to need medical care. The study compared the shot to a placebo to check both safety and effectiveness.
