Also, about 3.5% of the world's population already has it. That's about 300 million people for whom a vaccine is pointless, and who are at dramatically higher risk of liver cancer (somewhere between 15-50% lifetime risk of an extremely deadly type of cancer), and for whom a cure would literally be life-changing, if available.
