BA.4 and BA.5 hitting NSW, there on the right. Covid's latest trick is called 'imprinting'. Meaning if you get infected with an earlier variant of Covid, it imprints on your immune system. Which sounds great, except it makes your immune system respond to the previous variant, not the one you're now infected with. It then also weakens your previous immunity, from your prior infection. Similar to what measles does, when it wipes your immune memory to lots of other diseases as well. (This includes cancer.) Vaccination + infection (our current 'strategy') doesn't give you better immunity, it lessens it because it stops your immune system responding well to new variants. In a nutshell Covid is like a blender for our immune system. Like HIV.
