Faunsdale, AL | It’s not rare, but neither has it been common until the delta variant got cranked up this summer. Now it’s quite common for both recovered but unvaccinated and vaccinated people to get reinfected with delta. Usually the longer since vaccination or recovery, the more likely the chances of getting reinfected.
Immunity to a disease is dose dependent. If you have strong immunity (Antibodies) in circulation or in your nose you can resist all but the highest dose of virus you come in contact with. It doesn’t really matter where those antibodies came from, could be vaccination, could be from previous infection, but the levels need to be high.
Delta seems to be more “fit” for humans than previous strains and tends to make very high levels of virus, so more “immune” people loose the first battle in the nose and mouth and get infected.
They also have “memory” cells that can respond and make more of themselves and crank up the machinery to prevent the initial infection from progressing to more serious disease in the lungs.
The doctor you quoted seems to want to paint immunity as either you have 100% or you have 0. He knows better because NOTHING in biology is ever 100%. There’s always exceptions and more often than not, there’s a range of response clustered around a mean with fewer and fewer falling above or below the farther from the mean you get. In other words, the infamous bell curve. | |
