Grifols Hepatitis Program

I've known people who got treatments for hepatitis so I was interested when I heard about the specialty program to assist making medicine for such cases. I was curious if anyone else had ever enrolled and what the general details are. I know it's perfectly safe as they are more or less giving you the hepatitis B vaccine, but I'm curious to hear about experiences.

Were the shots done on the same day you came into donate?

Are there any long-term concerns to be had?

Did you feel fatigued or woozy after the shot and donation?

How did the compensation work and could you opt out of the program at any time?
