Hepatitis A Vaccine ?

[festus at wasatch.com]

I have heard of a new vaccine for hep A ( not gamma globulin ).   Does anyone have any information 
about this ? If so, I need it desperately ! Please remember that I am a layman, and any info that you 
might be able to supply needs to be in simple terms. Thank you.
