I guarantee that if they received antibodies from the vaccination(s?), they didn’t last. I think if people have received vaccines against COVID, they need to have an antibody test done at one month out, two months out, and three out. I was vaccinated, and I don’t have them.
I assume that is what happened here. All of these people who are “breakthrough” cases most likely don’t have active antibodies anymore, if they did at all. The lockdowns weakened our immune systems (on top of those like me whose systems are suppressed), so the vaccines don’t trigger the same level of response.
That aside, vaccines don’t always prevent illness, but lessen the severity. Like the flu shot, for example. That virus mutates annually, so there’s no real prevention available.
Where do you get an antibody test, and how much does it cost? Are you doing this for your own curiosity?
Have you noticed that a flu shot was never called a flu vaccine? Webster’s online dictionary had to add a new definition in order to make the mRNA shot be considered a vaccine. It should be called a “shot” just like a flu shot
