Newborn was scratched/bit by dog. small looking red scratch no bleeding. baby too young for vaccine. can she get tetanus? urgent care doc said no

Some basics: Tetanus is a secondary event after an infection from the germ starts & the germ begins to create tetanus toxin. If the wound is cleaned well & monitored chances of infection/tetanus are tiny. If a newborn's mother was properly immunized the newborn carries mothers immunity to tetanus for a few months. That is one reason the vaccines don't add protection when given so young.
