Panicing

Hello,

I'm not a nurse but a panicing new dad.

Here is the story.

My wife has given birth to twins on the 21st of this month. My wife was known to be hep. B positive prior to delivery. The babies were given a bath asap to remove any blood and were given immunoglobulin injections withing 2-3 hours of birth. However, the standard Hep. B vaccine injection was forgotten for some reason and only given today (24th), i.e. 3 days after birth!!! Is this way too late? Are my babies likely to get the virus?

Thanks for any help

Alex
