Here is ingredient lists for the different kinds (you can look up each ingredient by itself to find out what it is):
Hib/Hep B (Comvax)

As for the work part of it... not sure if it is illegal to force the vaccine on people or not as I am not familiar with the regulations there. However, where I am at, I could claim religious, philosophical, or even medical reasons for not getting it, and if an employee denied me work based on my beliefs and refusal to get the vaccine it could be potential discrimination based on beliefs.
It's basically are you willing to get the above vaccine for the work or not, and if you're not can you claim any of the exemptions in which they cannot discriminate against. Look into your local laws to see if there is a way around it.
I have had the Hep B jab (3 set) at 16... I had a minor reaction to it which resulted in redness, swelling, and I still have a bump on my arm where they stuck me with it. Besides that I have not noticed anything that could be tied to that particular vaccine.
