Epidurals, Pethadine and Vaccines!

I am fairly new to veganism and am expecting my first baby. I am of course a little scared in regards to labor and how I will cope with the pain. I have tried researching labor drugs to see if they contain animal products but am getting nowhere, and just keep going round in circles. If any of you have knowlege of any of the types of pain relief I would be very greatful for your advice, also in regards to Child immunisation. Time is running out fast though as I am due on November 19th!
Many Thanks! :flower:
