*Immunologic memory is an amazing and beautiful thing. For pathogens that don’t change much from one encounter to the next, it can provide us with lifelong protection. However, preformed immunity can come with caveats for pathogens that have evolved mechanisms that allow them to vary their antigenic structure. During secondary encounters with a pathogen that bears a strong molecular resemblance to an agent seen in the past (i.e., we have already developed adaptive immunity to some of the epitopes), memory cells specific for previously encountered epitopes are engaged rapidly and efficiently. As long as these cells and their products, like antibodies, can dispatch the pathogen efficiently, there is no need to mount a primary response to any new epitopes carried by that pathogen. In fact, the presence of antibodies attached to a pathogen, either as residuals from a recent infection or produced by reactivation of memory B cells, will divert naïve B cells from responding (Figure 17-4a). This occurs when the Fc region of the pathogen-associated antibody binds with Fc receptors on naïve B cells, inducing anergy.
Basically what that says is that when your immune system develops immunity to a specific strain that doesn't change you have LIFELONG immunity. Straight from a medical textbook, LIFELONG. Don't believe this bull**** you are being fed about immunity lasting only a few months. Lies!!! It also says that when your immune system encounters a virus that is very similar to another it has developed immunity to it will defer to those antibodies as a first attack on the new, somewhat familiar strain. Your body thinks "Why make some new antibodies if the old antibodies will work or will be a suitable base to modify current antibodies to handle the new strain?" Covid-19 has 2 strains. If you have had the vaccine and/or the actual virus for the first one you now have LIFELONG immunity to that specific strain and IF you caught the Delta strain your body would be one leg up already on creating effective antibodies. Once more, as I have linked below, this comes straight from a textbook used in medical studies. This did not come from Jim Joe Bob's medicine for stupid people blog site.
