This notion of first timer versus reinfection is a very silly one. How can someone who claims this is their first time catching COVID know that is actually the case? Did they test every day or even every week? It could be that they caught it before but it was nothing more than the sniffles which could easily be confused for seasonal allergies. However, this time with this particular variant it causes more symptoms prompting them to get a test which came back positive.
You get some immunity to a variant, yes, but at what cost? Plenty of studies are showing the COVID is causing
immunity dysregulation which ironically means those catching COVID are more likely to catch it again with worse symptoms.
Which we can now safely assume is in Australia, New Zealand and elsewhere. Frankly, I don't track variants anymore, I just don't care. What difference does knowing what all these variants and sub variants have on anything? The only prudent thing to do at this point is to mask up, particularly with high quality N95 respirators when you're out and about. It doesn't matter what variant is out there, the respirator will provide an excellent level of protection (the same cannot be said for vaccines, sadly).
Let me guess you had all Pfizer or all AstraZeneca? This has been the advice that so called public health experts have been telling us for a while now. I've ignored their warnings be it getting AstraZeneca as a (then) 33 year old and mixing and matching vaccines and I'm all fine. Thus far I've had five jabs (AstraZeneca, AstraZeneca, Pfizer, Moderna, Novavax). I test every week for COVID irrespective of symptoms due to my high risk status (immunocompromised with an autoimmune disease) and have tested negative thus far. I don't know if it's luck or the measures I've taken so far (respirator use, vaccination, vitamin D top-ups, etc.)
Yeah there's a lot we don't know about the virus and disease. I think it's important to keep a prudent attitude when out and about. By all means, do what you've done before, take flights, visit relatives, go to conferences, etc., but take measures to minimize catching COVID. Thus far since the "end of the pandemic" (at least in the eyes of the Commonwealth) I've taken 60 flights travelling all over the world from Oceania to North America and Europe. This notion that we have to choose between being COVID-free versus living a normal life has to stop!
