Yes, I think it is the gamma globulin shot. As Bill said, there was no treatment of any duration - just that shot.
Hi Cindy,
To my knowledge, Hep A doesn’t have a chronic phase, only an acute phase; and doesn’t require a therapeutic treatment to resolve it. I think sometimes dehydration can occur badly enough to require IV saline, but it universally resolves over the comparatively short duration of infection. Of course therapeutic vaccines for prevention are available for it now...
