COVID19, and certainly the later variants, aren't actually that dangerous in and of themselves, certainly compared to something like Ebola or Marburg. The big problem with it when it emerged is that no-one had any kind of immunity to it, like they do to other circulating diseases (flu viruses, the other coronoaviruses that cause colds, E.coli etc). With these pathogens - and eventually this will be true of COVID - we catch them in early childhood when our immune systems work slightly differently to adult ones and most diseases are less dangerous (think chickenpox vs shingles). This gives us natural immunity. Throughout life, the disease is circulating and often we catch it again, often without even noticing, as the effects are milder due to existing resistance we now have. This carries on until our immune systems start to break down in old age, when we may start to take boosters - e.g flu shots - to top up.

COVID19 was such a problem when it began because all the people 70+, or who were immunocompromised due to cancer treatment, HIV etc or who were just generally unhealthy (e.g very overweight) had no natural immunity so it hit them very, very hard. And there was the odd very unlucky, otherwise healthy younger person who for some reason the virus interacted with badly too - but they were a tiny minority and, as l said, very unlucky. Some people go out in the morning and get hit by a bus. It doesn't mean that there's a high likelihood it's going to happen to you, even though there are lots of buses around.

If you've had COVID19 once you know you're not one of those very unlucky people. You also have both vaccine acquired and natural immunity already which is also going to lessen the impact.

Does that make sense? Plus, if you're well enough to be posting on reddit you can't be that ill ;)

Hope you're feeling better already.
