Injections for baby

Two injections are offered to your baby in the first hours after birth. Here is what each one is for.

Two injections are offered to your baby soon after birth, a vitamin K injection and the first dose of the hepatitis B vaccine. Your consent is asked for at your booking in appointment, and again just before they are given.
