Is there a percentage data of breakthrough cases? Don't know squat about medicine but my money is on those people who were inoculated and came down with the virus had other things going on, like taking a prescription that weakens the immune system or they weren't perfect specimens of health either.Just FYI. I talked to my doctor last week to go over my blood test result. She is asking if I got my booster. I told her I prefer not to since I have a severe reaction after the Moderna second shot. She said that I can wait until I turn 65. She said Moderna is a little stronger than Pfizer which explains my friends that got Covid after the jabs were taking Pfizer.
None of the vaccines offer 100% efficacy so there are breakthrough cases from them all. Moderna is a stronger dose and may have less breakthrough cases but they still happen.
