You have that right! And what do you do about the booster? And I don't believe for one minute it gets weaker every year. I told my sister and brother-in-law not to get that shot they wouldn't listen and now they've got major heart problems and my sister has very weird symptoms from it. She's not doing well at all. I just cringe when people think they're safe to get that shot or any of those. It's hard for me to even talk about. When my sisters neighbor went with her to get the shot, the next day her neighbor was dead!
