Covid twice

[AyyX]

Not sure if there is already a thread on this but has anyone caught Covid for the second time or more? Just curious.
I think I caught it last year March but couldn’t test that time. Only symptom I had was lost of taste and smell, whereas my family had worse symptoms like fever etc.

First time March 2020. Had one vaccination. Have it again now, Delta variant. As Delta gets round vaccines I assume having had an old variant doesn't offer much protection either.
Symptoms very different. Much, much milder this time. First time was like bad flu, this was more like an annoying head cold. First time suffered horrendously with long covid for about a year. I'm more worried that will come back.
