I have heard rumors that a vaccine has been created for Hep "A" ( not gamma globulin ). If so, please 
let me know. I am seeking any information that might be out there on such a vaccine. please note: I am 
not well versed in medical jargon, so if you have any info for me, please keep it in simple terms.Thank 
you.
