I recall that in the early stages there was some talk that other corona viruses, ones that cause only common cold symptoms, were thought to give people some level of immunity to COVID 19. So if you've had Covid 19 varient Alpha, you should be able to mount a pretty good immune response to any of the varients based on that early 2020 observation about the other corona viruses.The variants are morphologically similar enough that there is almost surely some level of cross-immunogenicity, so while you might not be immune & can get sick, you will likely be substantially protected. This is the concept that sadly so many millions of people do not understand when they refuse to get the flu shot each year because, "they often get the strains wrong". They're missing the point entirely = another failing of the American public school system.
